Looking at the family trees on ancestry, I see that someone else has been researching Walter Freeman. I don't know if you've been in touch with the treeholder, - most probably you have.
I do hope you manage to make contact with your family here - keep at it. I recently have been reunited with members of my father's family after a gap of many years - wasted time, which I very much regret.
Here to help if you need look-ups going back.
