Hulda's parents were Samuel Brinsmade & Mahitable Hubbell.

I can provide you with a lot more information.
I have read that John Lyman (Laura's father born 1763) was a Revolutionary War veteran, but I have not been able to find any stories or information about this. If you have any, it would be appreciated.
