I am seeking information on Conrad Uhlenkamp, his wife Henrietta Wilhelmina
and his brother Martinus Uhlenkamp. The 1880 U.S. census indicated that
they were all from Hannover. They landed in New York on May 28, 1849 on the
ship Argyle from Leer. He was born April 25, 1824. His brother was born in
1819. His wife's maiden name was possibly FAYERS. She was born September
18, 1829.

Any information would be appreciated.
