Thanks so much for the extra information - I do have the marriage certificate and Charlotte's father is just given as Richard Pharoah, carpenter, again no middle initials and a different trade.
Can you tell me where you got the information on the probate from please?
Strange that his occupation if given as
Carpenter I havn't come across a Richard Pharoah with that occupation

This looks to be Richard with his parents
