I have a Bartholomew Ganley, born circa 1831 in Co. Sligo in my family tree, he was my great great grandmothers brother. I have his father as Bartholomew Ganley, born circa 1791 in Co. Roscommon, died 1840 in Lincolshire, UK and his mother was Mary Honara, born 1793 in Co. Sligo, died 1870 in Lincolnshire, UK. He had many brothers and sisters: John Henry, Elizabeth, Mary, Joseph, Anne, Thomas, william, James, Catherine. I'm not 100% sure I've got this right but let me know if this could be the Ganley you're looking for.
Cheers
Tracey
