So it appears that although they might have still been married, George Freeman and Ellen were no longer together by 1953. George Freeman could have moved elsewhere in Canada, back to England or just about anywhere, really. He doesn't appear to be on the voter's list for York area.
I wondered if daughter Barbara might have appeared on the voters list with him at an address to confirm his identity, but she married at age 20 or 21. I presume voting age was 21.
Do George and Ellen ever appear together on earlier voters lists? If not, it might indicate that their separation was much earlier.
