Monday morning update

I'm beginning to get a better picture of this now, i think.
The baptism of the Harry Dean in Hockley, Birmingham is definitely not the Harry Dean in Earth Pit Row. Following the Hockley one forward, he is still with parents George and Minnie in Shifnal in 1901 and as William henry in 1911. So, that's definitely not the one.
The Earth Pit Row man is the right one - but so far, I'm failing to link him to the Wiggins family. I'm beginning to wonder if he 'adopted' Eliza as his aunt in lieu of having a known next of kin when he enlisted.
None of the military documents list another name to link him to.
Thank you to everybody for the sterling help on this one, very much appreciated!!
Updated to add: There are a few Deans in Great Wakering in 1901: in New Road- brothers James 24, Albert 22, George 20 and sister Lily 18. They have a boarder, Harry FOX right age, for my Harry Dean, born in the right place. No mother's maiden name on the birth registration, and his younger brother, Charlie was born in Hockley .......
