In 1860, Dr. David was living in Brooklyn, New York with his wife Elizabeth and their children Christiana (b 1853), Alice F, (b 1854) and John W, (b 1858), His Real Estate was valued at $1,000 and his Personal Estate at $1,500. Elizabeth was born in New Jersey and all the children were born in New York.
By 1870, David was still in New York with his wife Elizabeth but only Alice was still living at home.
In 1880, David, Elizabeth and Alice had moved to Newark, New Jersey. David's mother's place of birth is recorded as Virginia and there is no record of his father's place of birth. Elizabeth's parents were recorded as having been born in New Jersey and Elizabeth as Pennsylvania which contradicts the 1860 Census record.
