Nicholas Harford/Hartford, b.c. 1676 and his wife Elizabeth Jenkins, b.c.1680, lived in Dover, NH.
They had 12 children all born in Dover from 1701 thru 1724.
There are numerous descendants going by either the surnames HARFORD or HARTFORD as well as the surnames of the men the women married.
My descent from Nicholas follows:
Stephen Hartford, b. 1707 Dover, NH m. Susannah Wentworth
Solomon Hartford, b. 1758 Rochester, NH m. Mercy Farnham
William Hartford, b. 1789 Lebanon, ME m. Apphia Shorey

Georgia Hartford, b. 1872 Blanchard, ME m. Thomas Rutland
Marjorie Rutland, b. 1911 Stamford, CT m. Joseph Oscar Johnson
Barbara Johnson (that's me)

Another descent I have from Nicholas goes down thru Solomon above, and then from his oldest daughter:
Alice/Elsie Hartford, b. 1776 m. Nathaniel Tuttle
Mary Burr Tuttle, b. 1800 m. Robert Perkins
Rachel Perkins, b. 1835 Rome, ME m. William Hartford, Jr., b. 1824 Lebanon, ME (listed above)and the line is the same from there down.

I have accumulated a lot of information on Nicholas's descendants and will share.
