I was contacted in the year 2000 by a gentleman in Wilmington, Delaware, who had purchased an old Sedgwick Bible. He sold it to me, and I began researching this family, starting with the Delaware census records. I found one John Sedgwick born in Delaware about 1794. The Bible belonged to James A Sedgwick (1865 - 1942), grandson of John, son of Willis.

Who is John Sedgwick? It is likely that he is one of the three sons of Joseph Sedgwick of 1800 DE Sussex.

In 1850, 1860 and 1870 we see his wife is named Charlotte. She may be a second wife. Her ages as given in these record indicata a birth date of 1806-1808, but that would make her 12-14 in 1820. Apparently in 1820 John's wife was age 26-45, and in 1830 age 20 - 30. It is possible that John's first wife may have died and he remarried between 1820 and 1830.
