On the records they are listed as Jarvis not Jervis. The marriage of Charles Jarvis to Sukey Heycocke was on 1st Jul 1771. They were bachelor and spinster. Charles jarvis was a compass maker. Witnesses were John and Elizabeth Heycocke.
Theres a baptism at St. Martins of a Charles Jarvis on 30 Sep 1749 with father Daniel Jarvis,
and a marriage also at St. Martins of Daniel Jarvis to Catherine Cooke on 4th Oct 1748 .... but I dont know if these are your family or not!
Thats about all I can see. Hope this helps a little. Shera[/QUOTE
Thank you Shera, That is the correct family. I had some of these details, but not Daniel's marriage details. I was trying to find out who Daniel's father was, I think it was Henry but can't be sure. Daniel was a compass maker as well.
