Thank you for all the posts and offers of help. I am learning more with each one. (Especially to watch my language!) I look forward to any future developments. Thank you everyone.
Dare I ask one more question? William Snr may possibly have been buried at Christ Church, Southwark. (Sorry, I do realise this is the Sussex board.) I have been advised that his body was probably removed due to overcrowding so the grave no longer exists. Does anybody have any idea what happened to bodies removed in these circumstances?
