I have Carrolls from Co Cavan(Hyland), Roscommon, Down(Heaney) and Armagh (Hughes). Patrick Carroll B. 1822 of Co Roscommon, married Mary Hyland of Co. Cavan . She was born 1830, Feb 18. She was from either Bally James Duff or Cullow. Not sure of town in Roscommon but Conaught and village of Fenry comes up in ancestrial notes given to me. I strongly urge you to partake in the DNA testing...lots of info and links to common family members.
