Since my last post I have made a discovery. The marriage of widow Sarah James to John Everitt was the right Sarah. On the Origins search site I looked for a male James who died around 1820's (Mary Ann Elsom Everitt, the daughter, was born 1831). I found a David James whose death is registered at St Leonard's Shoreditch in 1821. I checked and found a marriage to a Sarah Levens at St Leonard's. Knowing that the Elsom name came from somewhere, I checked to see if Sarah Leven's mother was an Elsom. What I found was a John Levens who was married to Sarah Elsom. So Sarah Elsom first married John Levens, then David James who died, then John Everitt.
I found a Sarah Susannah Elsom who was baptized at St Leonard's in 1814, born in 1798, no location listed. Her parents are John and Mary. They had several children baptized at St Leonard's but no marriage. I found a marriage for a John Elsom (Ellson) and Mary Vergo in Deptford, Kent in 1795 with a daughter born there in 1796. So, it is my theory that this couple moved to the Shoreditch area about 1800 after 2 daughters, one of them Sarah, were born in Deptford. In Shoreditch they had several children born and baptized.
The marriage for Sarah Elsom & Jon Levens was at Finsbury. The marriage for Sarah Levens and David James was at Shoreditch. The marriage for Sarah James and John Everitt was in London. So all are in a close area. So I am assuming her family was in that area also.
Actually I am assuming a lot, but everything has lined up. It would be great to find some documents to prove all of this theory, but as of yet I have none. I have looked for family of John Elsom/Ellson and Mary Vergo/Virgo. But I have not really found anything on them.
If you know of a John Elsom born about 1770's in the Kent area or around the London area, please let me know.
