The Blennerhassett problem - Things to do


Things to do - Blennerhassett problem

Now that DNA says our line is the Blennerhassett Baronets, we need to re-examine everything about the Baronets branch. Especially the 1st Baronet and his wife.


  1. Exchequer Court of Equity Bill Books, 1674-1850.
    • Ancestry
    • Search for Rahilly, Blennerhassett, Cashel.

  2. Letters from Theobald Butler, Sept and Nov 1824, [CSORP]. Does he name his father?

  3. Business Records Survey no.117

  4. Search for Caleb Chute will 1851.


  1. CSORP searches - Butler, Yielding
  2. CSORP searches - 1834 on - Blennerville, Churchtown, Blennerhassett

  3. Blennerhassett in [Crossle Genealogical Abstracts]. Does not look relevant.


The Baronets family had lots of wills, but almost all were burnt in 1922.
  1. DONE - Searched all Blennerhassett wills in:

  2. Testamentary index cards have:
    • No Yielding wills.
    • No Hurly wills.

  3. [Jehan] says transcripts exist of:


  1. Hurly in [Denny, 1923]
  2. HURLY in Crisp's Visitation of Ireland
  3. Eagar, 1861

  4. Trinity College Estate, 1800-1923, Robert MacCarthy, 1992.

  5. The College: A History of Queen's University College Cork by John A. Murphy, 1995.



  1. Rowan papers

  2. Hurly in Ms 8316 (15).
  3. HURLY in Crisp's Visitation of Ireland

  4. Eagar - Re-visit [Ms 4112]

  5. [NA.UK] has an unusual entry in Discovery: Blennerhassett family, baronets, of Blennerville. Family and estate papers. 18th cent-19th cent. Held by: NLI. See MS sources for the History of Irish Civilization, supplement 1965-75, 1979.
    Cannot see this in NLI catalogue.


NLI offsite

  1. Find BLENNERHASSETT in Debrett's Baronetage before 1828.

  2. Arthur Blennerhassett of Blennerville is mentioned in connection with schools in Blennerville 1824 [Heritage Council, 2001].


Letters of any Co.Kerry gentry family around 1806

If there was a Rowland Blennerhassett scandal around 1806, almost any Co.Kerry family might mention it in gossip.

George Cashel in letters / politics

  • George Cashel is apparently supporting Home Rule politics at Carlow in 1879.
  • According to my theory, his 1st cousin's son Rowland Ponsonby Blennerhassett was elected Home Rule MP in 1872.
  • Maybe George wrote to him?

  • Note that Letitia Blennerhassett (Hurly) is of the Home Rule line. Though she died long before Home Rule times. She died before 1834. She is grandmother of the Home Rule MP. She may be George Cashel's aunt.

  • Records of Home Rule association at Carlow?
  • Newspaper search for meetings.

Blennerhassett Cashel in letters / politics

Blennerhassett Cashel knew Stephen O'Mara, Home Rule MP.
He knew David Sheehy, Home Rule MP.
He was apparently 2nd cousin of Rowland Ponsonby Blennerhassett, Home Rule MP.
He was apparently 2nd cousin of Sir Rowland Blennerhassett, 4th Baronet, Liberal MP. He went to a talk by him.
Did he correspond with any of these? Was he interested in politics? Does he appear in any letters?

  1. NUIG - Rynne papers

  2. UL - Stephen O'Mara the younger papers
    Partially consulted. Images photographed.

  3. David Sheehy, MP letters
    • Sheehy Skeffington Papers. [NLI] Ms.

  4. Rowland Ponsonby Blennerhassett, Home Rule MP letters
    • He was alive in 1900 when James O'Mara became Home Rule MP. Wonder did he write to James, who had married (possibly) the dau of his 2nd cousin.

  5. 4th Baronet, Liberal MP papers
    • Did (his 2nd cousin?) Blennerhassett Cashel of Cork correspond with him when he was President of Queens College Cork?
    • For 4th Baronet papers from Queen's College, Cork, period, try reading the histories of UCC.
    • 4th Baronet was alive in 1900 when James O'Mara became MP. Wonder did he write to James, who had married (possibly) the dau of his 2nd cousin.

Blennerhassett Cashel was involved in the following. Find records:

  • Catholic Institute, Limerick, 1892. He was apparently Secretary.

  • Cork Catholic Young Men's Society (or Cork Young Men's Society), Cork, 1898 to 1904.
    See Cork Catholic Young Men's Society - A History - 1852 - 2010. See advert.




Other Dublin

  1. [TCD]

  2. [UCD]

  3. [DCA]
    • Find source for the Richard Yeilding entry in [Dublin directory, 1738].
    • This is a special modern compilation from various sources.
    • Think the Richard Yeilding entry is NOT from Watson's Almanack. It has no general list of people at this stage.
    • The Richard Yeilding entry might be from the collection of bail bonds of Apr-Sept 1738. Now in DCA.

  4. GROI


  1. Chute papers
    Have searched SL/B/1(1-12).
    Do rest of SL/B/1.

  2. Collins papers again.

  3. P30 Blennerhassett papers
    Seems to be mainly Blennerhassett of Ballyseedy, but family tree may show other lines.

Other Ireland

  1. Local custody - St.Mary's Cathedral, Limerick, par records.

  2. Dromavally, Killorglin

  3. Baronets graves


  1. 4th Baronet papers

  2. [BL]




  • DONE - Looked at all Rowland Blennerhassett in 1758-1821
  • DONE - Looked at all Robert Blennerhassett in 1800-1809
  • DONE - Looked at all Baronet branch names in 1804-1859


Searching for Baronet branch deeds

  • Robert (d.1766), Frances
    • Rowland (d.1821)
      • Millicent
      • Richard (d.1817), Agnes (d.1842)
      • Robert (d.1831)
      • Arthur (d.1839), Helena Jane (d.1846)
      • William (d.1842), Elizabeth (d.1857)
      • Rowland (d.1854), Letitia (d.pre-1855)
    • Arthur (d.1790), Catherine (d.1810)
      • Robert(d.1814), Catherine (d.1841)

  • Find wills / will substitutes for Millicent's siblings.
  • In a multi-person deed, the name it is listed under in the index is often fairly random. This is true for both the Grantor and Grantee side. Just need to search anything remotely plausible.
  • (todo) Search for other Kerry surnames as Grantor to Blennerhassett.


To do

  • Mark all searched deeds in yellow in table.

  • Do similar table and search for all YIELDING / YEILDING deeds.
  • Search BUTLER of Waterville/Belville. Going to be hard. Too many false hits.
  • Search HASSETT.

  • View originals:
    • Arthur Blennerhassett marriage settlement, 1799. His mother Millicent Agnes Yielding was apparently alive as at this deed. Online image is illegible. See original. How is her name spelt?
    • [Deed, May 1795]. Online image is obscured. See original.
    • [Deed, apparently 1789]. Online image is hard to read. See original. Is it really 1789?
    • Rosana Blennerhassett in Grantors Index 1816. Reference is illegible online.

  • Find these:
    • Godfrey to Blennerhassett, 1788. [Deed, Dec 1802] refers to a deed of 25 Mar 1788 from Edward Godfrey to Rowland Blennerhassett about the house in Tralee where the 1st Baronet then lived.
      Searched Godfrey in Grantor index 1788 to 1792. Not found.

    • What appears to be yet another Deed of 25 Mar 1804. Richard Blennerhassett of Ballymacprior and Richard Chute of Chute Hall and Richard Blennerhassett of Blennerville. Transcript in [Kelly and others, 1989, p.396].
      Searched Blennerhassett in Grantor index 1804 to 1809. Not found.

George Cashel at school

  1. Find listing of school children 1810-28
  2. Blennerville or Churchtown

  3. Erasmus Smith school, Blennerville
  4. Erasmus Smith schools archive says about Blennerville school:
    • Founded 1811. Patron Sir R. Blennerhassett
    • Architectural plans exist 1812
    • Property documents exist 1812-1840.
    • No correspondence exists. This means no list of pupils exists.
    • Discontinued (from Erasmus Smith system) 1839. New school built 1840.

Letitia Yielding theory

Other theories

  1. Arthur of Fortfield had a natural dau Elizabeth
    • She mar pre-1798 to Denis Murphy.
    • Maybe Murphy died and she then married Cashel?
    • We would then be looking for the marriage of Cashel with the widow Elizabeth Murphy, having issue George Cashel, born 1807.

  2. Oliver Mason Creagh mar Cashel
