Do you know whether he had any other initials? Alternatively, the name of his wife and/or children? I am looking at a possibility but need a few more clues.

Sorry for the slow reply! I've been busy with academia....

Above is the information that was sent to me by my great-aunt, I personally found it quite confusing; but it's all I've got to base the research of my mothers family off of.
I'm not too sure where the 'Florence'/'Dalrymple' surname popped out of or why it was changed

She (my great aunt) has also been pretty persistent about the whole 'Emily Davison' relation - but it would seem her spelling of 'Davidson' is different, so not sure how true that is.
Not very helpful I know! But I would seriously appreciate any clues or just a general push in the right direction.
