The Hessom name is rare and unusual. If you are researching the name also, it probably means we are related and I would love to hear from you.
The first record of the name I have been able to locate is in 1816, in Allegheny Co, PA, when Isaac Hessom purchased a tract of land in Moon Twp. He is found in the same place all the census reports through the time of his death.
The family seems to have originated in Germany, but I can find no record of their immigration or naturalization. The name is spelled many different ways in the records and makes tracing them difficult. The main variations seem to be - Hesson, Hasson, Hassom, Hissom, Hisson, and Hession.
