Its odd writing to another stewart parsley, even if spelt diferently. I may be able to assist you but you do not supply a lot of information. Is Henry, just Henry or has he any other names ? do you know how old he was when he died, where he married or where he was born , and is there any other family members.
My family lived in London from about 1850 having moved from farming and retailing in Norfolk. I have spent many years indexing all the Parsleys I have ever found and if you can find any information on your family prior to 1900 I am sure I will have some information.
