Thank you so much for all your sterling work! I've been pondering over this for weeks.
John Corden named his daughter Millicent, (my great grandmother). I always wondered where that name came from!
I noticed the Baker family on a census record but I really wasn't sure if there was a connection or not but i think you have all confirmed that there is.
He died very young, aged 32 so there aren't that many records to search, although I know he was married in Essex,(he was in the Royal Artillary), so I could send for the marriage certificate, but I have learnt more about him today than in months of searching.
Thank you everyone!
And thank you Phillip, I will try what you suggested.
