Like to have all my ducks in a row, helps me lay out a plan on the best way to start any research. These things, you probably know.
Let me know what may be true.
Your grandmother married James, on Nov. 23, 1935, they lived in Manchester, NH.
Louse passed away July 13, 1996 at Merrimack.
In 1920, your grandmother was at a place called Webster Place, Franklin, NH.
In 1919, she was at the Rockingham County Farm at Brentwood, NH.
She was there with her siblings:
Joseph born about 1906
and her sister Katherine born about 1909
Parents are listed as being born in Vermont.
If the is true her parents may have been Joseph and Louise. If this information is true, then something happened, that drove the couple apart.
Let me know what may be true. Plan to go to Brentwood tomorrow to begin the dig. Will do my best to get you a picture.
Do you have your grandmother's obit? That would also be a very good place to start.
