In 1870, a Bridget O'Geary is listed with the McCarthy family as a housekeeper. I suspect her to be the mother of Mary, husband of Michael.

The census listed County Cork as the birthplace of Michael, and County Sligo as the birth place of Mary and Bridget.

There was another McCarty family in Hanover that I think may be related. Head of house was Owen, wife Mary. And in 1860, there is an older Mary McCarty living with them, which I suspect is Owen's mother.

Mary Ellen McCarthy is buried at Dartmouth College Cemetery

According to her death record, Theresa is buried there as well. There's a reasonable chance that John is also.

Also a good chance that this is John's parents with some siblings...

Here is a Mary Hennibery living in Northfield, Vt in 1870, which seems to fit. Mary O'Brien's death certificate does list Northfield as place of birth.
https://familysearch.org/pal:/MM9.1.1/M6R6-W88

It appears that Bridget Potter may have been married twice. The question is whether Patrick O'Brien or James Hennebery was first. There is about a 7 year gap between Mary and her sister Elizabeth. It's possible that Mary was an O'Brian and James was her stepfather. It's also possible that James was her father and that perhaps Bridget later married Patrick O'Brien. Given the reference to Patrick on Mary's death record which I presume was provided by husband John, I'm inclined to think that Patrick came first and James came second, and the Elizabeth/Lizzie is her half sister. Need to see Bridget's marriage records to confirm

Here is the birth record of Mary's sister Elizabeth...

Possible death of James...
https://familysearch.org/pal:/MM9.1.1/XF3F-CR9
I'm quite certain this is James, the husband of Bridget and father of Lizzie. The death is recorded in Waterbury. James apparently remarried, to Mary Spellacy Sullivan in 1877 (her second marriage as well) in Colchester. Mary and Lizzie can be found in 1880 living in Waterbury with Mary's family.

Thanks this sheds a lot of light on who is where. I do have a death certificate for mary in the new hampshire death record and it lists Patrick and Brigdet potter as father and mother. I belive that you are right about Briget Potter remarrying thanks so much again

Yes, no doubt. My postings may be a bit choppy since I would edit and add info as I went along, but Patrick, Bridget and Mary were in the 1860 Census and then Patrick died in 1861. Bridget then married James, and had a daughter Catherine.

I did have some of the information but no all that you brought to light. I have a relative who live in hanover and should be able to get over to Dartmath cemetry and find the graves of John, Mary and theresa.

Thanks again
