The tradition in our family is that the Flanagans were from Co.Roscommon and moved to Co.Dublin.
Frank Flanagan
said there was a story that  the Flanagans were stewards to 
The O'Conor Don
at Clonalis House
(or Cloonalis), Castlerea, Co.Roscommon.
The original Clonalis House  was     early 18th century.
See
 [Irish Country Houses].
The old (early 18th century)
"Cloonalis House", Co.Roscommon,  on
1829 to 1842 map. 
 
There was a story that the Flanagans were stewards to The O'Conor Don here.
But there is no evidence to support this yet.
This house is now gone, replaced by the new
"Clonalis House" (built 1878)
a bit to the N of this site.

Tallaght and Clondalkin parishes    in
Petty's Census of Ireland, 1654-1659.
From p.377 of the 1939 publication. 
See Kilnamanagh  in Tallaght par, 
and Corkagh  in Clondalkin  par. 
Perhaps before Flanagan even came to Co.Dublin.

I have    spent   a great deal  of  time and money on this research.  
  Research     involves   travel     and  many    expenses. 
  Some research   "things to do"  
are not done  for years, because  I do not  have the money to do them.
