At first it seemed that the only reference I had to your Jonathan and Matilda was from the entry in the 1881 census:
Descendants of: Jonathan/Johnathan Waghorn
1 Jonathan/Johnathan Waghorn b. c1842 Dartford m. before c1869 Matilda ? b. c1842 Deptford 1881 census shows Johnathan, 38, Barge Captain, wife Matilda,38,Mary L,12, Johnathan,10,Matilda,5,& Minnie A,3,at 4 Flint Cottages, Craylands, Swanscombe. 2 Mary L. Waghorn b. c1868 Plumstead 2 Johnathan Waghorn b. c1870 Swanscombe 2 Matilda Waghorn b. c1875 Swanscombe 2 Minnie A. Waghorn b. c1877 Swanscombe
Then I decided to look again at the other Jonathans in the main database, and struck pay-dirt!The following one, who was christened in Dartford on 29-Jan-1843, is almost certainly the same person, with a probable marriage in 1866, which fits with the birth of Mary.This takes us back another two generations, and then another probable match goes back another two!This means a good deal of output, so I suggest you contact me at firstname.lastname@example.org and I will e-mail it to you direct.
