I have the marriage of Edmund and Ann on file, but nothing on their origins.
However, I do have quite a bit more about the family, including (in my files since 1974 and almost forgotten) a photocopy of the will of the son Edward.
This is interesting on several counts.I don't have a detailed transcript, and it's too big for my scanner, but here are the notes I made all those years ago.
INDEX (Kendal Deanery) Edward Fishwick, Heysham d. 10/Aug/1830 Exec.Elizabeth Fishwick (widow) Inventory:under £2,000 Notes from the will itself: Edward Fishwick married Elizabeth Carter Was son of Edward Fishwick, Limborner [sic] of Nether Kellet Had sisters: Margret marr. Walker Easter [sic] marr. White Catran [sic] marr. Heyes Betty marr. Fairclough Ann marr. Tenpeney
You'll see that his father is called Edward, not Edmund - a very common scribal and transcription variant - and was a Lime-burner ("limborner").There are also three more daughters to add to your list.I guess that "Easter" probably should be Esther, and "Catran" probably Catherine.Elizabeth was apparently known in the family as Betty.
