Mary Jane McKeown
Hi Michael
My gggrandmother was Sarah McKeown (m James Hamill in Glenavy 1862). Sarah's parents were Arthur McKeown and Mary Jane McKeown. Her siblings were as follows:
William John
Arthur
Margaret
Sussana
Dorothea
Ellen
Esther
Her father, Arthur, died in Ballyutogue, Templepatrick, Co Antrim (2/7/1861). These details were found on a genealogy site called "Rootsweb" on the Hamill message board, in a message dated 2/1/02. Hope this may be of some help. I know the years are a bit out but maybe your Mary Jane was a niece of my gggrandmother, Sarah.
Regards
Anne Marie
ps Message is in McKeown message board - other names mentioned are Arthur's granddaughters Margaret and Mary Jane Graham, his niece Sarah Jane Kerr and his son-in-law James Watters.
