Hello Mary,
Agnes is my husbands great grandmother. My mother in law remembers her talking with a "brogue". (sic) I haven't found a marriage date for James and Helen but I may have found who Helen's parent's were. As for James birth date, I found James, Helen, daughter Helen and numerous grandchildren in the 1881 British Census and his age is listed as 66. As census go, that could be right on or way off. I've checked the IGI files and can't come up with a marriage. You said Hugh came here in 1888. William came in 1871 and Agnes said she came in 1874. She married James McConnell in 1877. You gave me a huge bit of information. I didn't know who James' parents where. Still trying to track down Martha who married a Cossar and resided in Africa. Do you know anything about her? Will gladly share what I have.
Sandi
