Thank you all for your responses.
The reason I know it's Hubert John Hawkins is because of the newspaper clip of his wedding to our ancestor Phyllis Mary Crawford (attached). I know she remarried another soldier (William Van Horne) but did not know why and - this second marriage happened in 1956. The military pension card in my OP came from an Ancestry hint. That's the only information i have and am searching for more, including birth records, marriage records, etc...
So am I to understand there are two individuals with the same service member?
