There are 2 main branches of the Hildreth family, one in New England, the 2nd in Long Island (New York) with a 3rd in New Jersey. Many myths are floating around about the two main branches, New England line goes back to a Richard Hildreth, Long Island goes back to a Thomas Hildreth.

The geneologist for the family is Richard Hildreth and you can find him by going to the family website, just google for "Hildreth Family Association".

It would be very useful to include whatever else you can about your mother and her ancestry.
