Looking for any information on David B. Ewan who was born in NJ around 1829. He married Hettie J. Sweeden in 1880 and had at least two children Carrie L. (b. 1881) and David J. (b. 1886 - d. 1890). 1870 Census has a David B. Ewan living with father (?) David A. (b. 1791) and mother (?) Rachel (b. 1797). Thanks.
