William Seabrooke ^340,493

  Research Notes:

Research from the LDS IGI files.
A James Dyson married Mary Ann Seabrook at St Clement Danes, London on 4 Apr. 1808.
A Mary Ann Seabrook daughter of William and Mary was b. 21 Sept 1786 and christened at Saint Mary, Stoke Newington, London but I can find no equivalent entry for Elizabeth Seabrook.
[But this might be the William Seabrook, father of Elizabeth Seabrook , born about 1796]
