Sir Rowland Blennerhassett, 1st Baronet

Unknown portrait inherited by the 7th Baronet.
It is possible this is the 1st Baronet. Though it might be some other ancestor of the 7th Baronet. It could be an ancestor of Morgan. It could also be one of the Ballyseedy Blennerhassetts, whose property the 7th Baronet inherited.

Rowland built or lived at Churchtown House, near Killarney, Co.Kerry.
Rowland Blennerhassett is addressed at "Killarney" in letter of 17 April 1788. This is probably Churchtown. Certainly he is at Churchtown the following month.
He is listed as of "Churchtown" in [Deed, May 1788] and [Deed, March 1789] and [Deed, Nov 1789].
He is listed as of Churchtown in the will of his brother Arthur, Apr 1790. This was registered in 1806 but think the addresses come from 1790, not 1806.
He managed his brother Arthur's estate after his death, 4 May 1790. This is noted later in his nephew's marriage settlement, May 1798.

Tree in [Ms 20621] (c.1909) repeats the same.
[Kelly and others, 1989, p.44] and [Blennerhassett and Hollwey, 1991] say she was killed in 1801.
Oral history in the [Schools' Folklore Scheme, vol. 440, p. 140] collected in 1937-1939 says she "went up on the balcony of it. It was working at the time and the wind blew her in and she was ground to pieces."
Bill Jehan says: "She is said to have [been] killed by a blow from a turning windmill sail as she looked out from an upper door ... In times past, before the windmill became derelict, it is said that her name and perhaps the date were inscribed in the woodwork of the door frame where this accident occurred."

Proposed to be a Baronet: For some years, James Crosbie, MP, of Ballyheigue, made representations to Dublin Castle that Rowland should be created a Baronet.
See letters of 1804-1805 from Sir Evan Nepean (Chief Secretary for Ireland 1804-05) about Rowland being proposed for High Sheriff of Co.Kerry, and then proposed for a Baronetcy.
