Seeking further information on Jehudah Ashmun. My 4ggrandmother, Charlotte Royce/Rice Thompson (1778 - 1868), born the daughter of Jonathan Royce and Mabel Bristol in Lanesborough, Berkshire, MA, left a list of her relatives. One of these was "Jehudah Ashmun, my brother-in-law." Since this couldn't have been the husband of her husband's sister, he must have been her own sister's husband. There are two possibilities: Mary Royce/Rice, b 1764 in Woodbury, Litchfield, CT or Mabel Royce/Rice, b 8 July 1771 in Woodbury, Litchfield, CT.
I have found a Jehudi Ashmun, a boatbuilder, as I recall, in the upper midwest, but he is at least two generations removed in time.
