Letitia was my 3x Great Grandmother and as yet I have not found a birth record for her, only her baptism. Neither have I found any record regarding John Brain as yet.
I have read Edmunds will and I'm now in the process of transcribing it. It would also seem that his son William left a will and I will be sending off for that soon. Here is the probate notice:

Fletcher William died 16 Jan 1916. Probate 2 Feb 1916 to George Fletcher Collier and George Morgan Collier. Effects £137 os. 11d
