Hi Pete,
I have to make a few more posts before this site will allow me to PM message you as your email address was removed by the moderator.
The grave record from Glasnevin shows those who are buried there and their relationship
to the grave owner John Gourley:
Anne Gourley died 13/02/18 aged78, blank
Marion Athorn died 16/04/36 aged 70, sister
Elizabeth Gourley died 03/04/49 aged 75, sister in law
Julia Reid died 23/04/52 aged 67, sister
John Gourley died 04/06/52 aged 81, owner
Christophe Gourley died 15/08/80 aged 69, nephew
Lucy Gourley died 31/10/85 aged 77, niece
There is also a posting on ancestry.com regarding a daughter born to John Gourley when he lived in England. Unfortunately I don't think the rest of the family were aware of her existence as he didn't marry her mother.
Who was your grandmother/father from Anne and Philip's children. What country are you bsed in.
Regards
Mary
