Hi...no...we are pretty sure it is Thomas MATTESON, d. 1752, 2) Thomas M., 3) Mercy Matteson, who m. my Francis BRIGGS. There is a great book on the Mattesons....I found it over in Las Vegas, just a small book....named...."Mattesons in America." I have used that, along with other sources, for a few years. Get in touch if you need further info. My line is the one that connects to the PLACE/HUTCHINSON families...and the SHIPPEE family. Barb By.
