Thanks for taking the time to look for this address.
It was a Mrs Eva Higginson, 13 Belgrave Terrace, Soho Rd, Handsworth, Birmingham. She lived there during WWI as Sidney John Winkles was sending her monies. He listed her as his sister on his pay stubs. But we have no records of an Eva nee Winkles married to a Higginson? We know he had a friend named Sidney Higginson? This is a real mistery!!!
