there was a richard killinger m 3.5.1702 to Sarah Harrison at Sutton on Trent Anne was chr 1.3.1702 at same place
i found a probate for newark dated 24.5.1749 of a Charles Godard bequeathing amongst other things some money to the sons of John Killinger.
i then found christening at Newark William m 1.1.1679, Thomas chr 3.7.1712,, Sarah chr 31.8.1710.
then John m 4.12.1753....at Norwell & Carlton on Trent. Funnily enough i then recently found a whole lineage in Ireland that divided into two branches... one was an architect and one was a carriage maker.
I found a lot of material in British Newspapers Archive family notices articles and the like.
