Margo,
William Henry (b. 1753) married Sara/Sarah Barnard (b. abt. 1755 "of Lyman MA") both buried Hinesburg VT he in 1829 and she in 1835. We believe that Sara/Sarah's Barnard family was from CT as her 7 brothers fought in the Rev. War.
Sara/Sarah had a twin sister, Elizabeth.

Henry C. Howden, their youngest child, (b. 1792 Peterborough NH) m. Abihail Munsell (b. 1795 Bristol, Addison, VT) settled in Allegany County NY after marriage in 1812 possible Salem MA as the older children born there. Abihail d. 1869 and Henry C. died 1885 both Fillmore, Allegany, NY.

I hope this clarifies it a bit--it was not very clear in the posting. Thank you for your inquiry.

Vicky
