Hi there and thanks for the advice. It's all new to me so i'm not quite getting the hang of it.
This is what i have already ..
Henry McShane and Mary Coyle both born 1820.
They had a son Henry McShane in 1848 (don't know about other children)Died 1917
He and his wife Mary Toner went on to have a son John Harper McShane in 1871 died 1936
John and his wife Janet Nicholson Sanson went on to have a son Gilbert Sanson McShane 1900 died 1967
He and his wife Annie Gemmel Ferguson then went on to have a son Henry McShane who was my father in 1942 died 1999
I have some siblings in notes of the sons, would that help or is what i have provided enough for a search ?
Thank you M
