Not sure what the order of the words should be but I think it is:
Uncle Will Brother Mickie
W Booth JEH 29/8/27
Noting that Mike suggested Matthew I think he may be right, so Mathew rather than Mickie.

Perhaps it is:
Uncle Will
W. Booth
Brother Mathew
Then initials and date.
I am just wondering if the brother Mathew was added later as a bit of extra family history, because the word brother looks like it has been squeezed in.
Do you have a William Booth in your family tree?
