Oh yes , missed that.
But our chap was only 19.
So whoever wrote it on the photo was wrong on either the date or the age.
If the age is right (21) then he cant have died in Dec 1901
If the date of death is right, then that York one might be him, but he was 19 not 21
If neither are right, them he could still be alive in 1938!
It would be so helpful to know if the op is wanting to trace these children forward, or the Chadwick and Crowe families back further than he/she has already found. Either way it would be helpful to know what he/she already has.
I started with the census of Thomas and Emma and children, but tben re-read the op and realised he/she had already got places of birth and parents for Thomas and emma, so thought I was probably repeating what was already found.
But I dont know!
