These are as many details as I know on the places: Susan ADCOCK married John POND - son John (see marriage below)born in 1804; John ADCOCK married Elizabeth PLASKETT in 1798 (St Georges in the East, London), and had the Mary below; John POND married Mary ADCOCK in 1825 London (St Michael Royal). Their last son, Wilberforce was born in 1840 in Bishopsgate. The above Susan and John (Snr) are siblings. Other siblings were James, Betsey, Elizabeth, Mary and Daniel. Their parents, Daniel ADCOCK and Mary CLARKE were married in Luton, Bedfordshire, in 1764.
Some of this is from the censuses, in which they people frustratingly said they were born in "London".
