Margaret Divers never remarried from what I know.
Margaret (Divers) Connell passed in 1946, on December 25th.
I'm having a helluva time tracing her as well, she was born in the States, her mother became ill and her father took her and her brother (unnamed) to Mayfield, Cork, Ireland to be with her mother's family.
Her mother got better, her father died in Ireland. Her mother remarried a man with the last name Jordan and had 2 kids before coming back to the States.
However, according to the story, Maggie was around 16 the first time she met her half-siblings, so she likely came back before her mother did.
Maggie was born in 1877, January 21st I believe is the date.
I can't locate her in the 1880 census, but it's possible she was already in Ireland.
Her parents names were Hugh Divers and Hannah Mulcahy, and Hanna Muclahy's mother's maiden name was Sullivan.
What bothers me with Maggie is that I know she had a brother, but not his name. I know she had 2 half-sisters, but have not been able to trace them either. One died at 20 during childbirth (Irene?), the other lived on Maggie and her were close (May).
