Hi Jon, My name is Nancy Danneberg Gates, and Andrew Hamilton Rehbein, was my great Uncle. His mother was Ella Barnhill Rehbein. Andrew was born In Baltimore, in 1886. Andrew had a brother George b. 1888, a sister Elizabeth (Bessie),b.1890,sister Margaret b.1891 and sister Helen (Nellie) b.1893. If you will check the 1900 Baltimore census, you will see all listed.
