My connection to the Allard family is through Martha Ellen (didn't know her middle name before!) and Nathaniel Place.
I have a copy of Nathaniel's will, bequeathing a good chunk of his estate to Martha, as well as a picture of her headstone.I will be happy to share those.
My Place line continues with the youngest son of N & M - Daniel N. Place.
I am very curious about the Allard's trip to Ohio, as Nathaniel and his family also left the Durham area and went to Ohio via Vermont, but through Chittenden County.Caledonia county is out of the way when one is traveling westward...
I would love to help you document or fill in research gaps.If I can be of help, please let me know.
