Scammahorn Family Genealogy Forum
I noticed several Schamerhorns listed in the Social Security Death Index from Iowa. This last name is very uncommon (especially this spelling). There are also a few listed in Washington and Texas. My wife's family is from TX but before moving to TX they were in the Northwest corner of MO and have one child listed as being born in Iowa in 1875.
The earliest I know of this family is John Schamerhorn b.1842, OH and his brother Hiram Schamerhorn b.1835, OH.
I'm sure this family is from the Schermerhorn Family of New York; but have not found the connection.
