I think we have a connection. I'm researching my husband's family, and his great-grandmother was Elizabeth Jane Forder. I think this must be the same family because Elizabeth's parents were William John Forder and Emma Ann Messer and they had 7 children that I know of - Eliza Jane (I think she died young), William John, Elizabeth Jane, Ann, Sophia, Emma and George, so the names tie in with yours. They lived first in Deptford then Rotherhithe.
Elizabeth Jane Forder married George Knowelden in 1875, and I have to admit Ive concentrated on his family not hers so I don't know much about the Forders.It would be interesting to find out more.
