Hello Lynnmart
who are the witnesses on that marriage cert of 1866 Pancras R.D between Martha Salisbury & George King?
who are the witnesses on that marriage cert of 1886 Pancras R.D between James Hall & Elizabeth King?
Sorry..............the 1861 census for 2 Middlesex court states Isaac Salisbury as the head of family...not Jake or John..........that doesn't mean to say that he is not Isaac John or John Isaac but Isaac it is
IN FACT................
Isaac is 63 years old and he was born in Henly, Oxfordshire according to the census
Mary is 43 " " she " Hambleton, Buckingham " "
If he switches between names this may be him below..........and he might have married the lady with him?
1841
STEEPLE ASTON, OXFORDSHIRE
JOHN SALISBURY 50 Builder (looks like?) Y
MARY HOWSE 20 Y
