Sweeney, Regan & Sheonane -- Raheelin & Tullintaggart (early 1800s)

Hello, 

My GGGF Bartholomew (Bartley) Sweeney was born around 1837 in Raheelin, Rossinver, Co. Leitrim. 

Bartley married my GGGM Honor Regan (~1846-1919) at Glenfarne Church in Manorhamilton on 23 Nov 1868, and they had 6 sons (Patrick, Michael, Francis, Roger, Bartholomew, Myles) & 1 daughter (Honor). (Marriage record attached.) Bartley died 9 May 1893 in Tullintaggart, Cloonclare, Co. Leitrim. 

I am searching for info on Bartley's parents. I think their names were Patrick Sweeney & Mary (possible maiden name Sheonane?). I believe they lived in Raheelin. I don't have their birth or death dates (though I have reason to believe Patrick Sweeney died *before* 1868). I believe Patrick may have had a brother Terence Sweeney (died 5 Dec 1892), who is listed as a witness on Bartley & Honor's wedding record. 

I am also searching for any info on Honor Regan's parents, who I believe lived in Tullintaggart. I believe her father was Michael Regan, and I believe her mother's first name was Honor & she died on 24 Feb 1882 in Tullintaggart.

I've really gotten stuck in my research, and I'd be thrilled with any help or advice anyone may be able to give. It's also worth mentioning that "Sweeney" is spelled with & without the final "e" in various documents.  

Thanks so much!

Rob Sweeney
