Hello Barbara,
I know this is an older post, but I'm hoping to connect with you.
I have been trying to trace my g-grandfather, Arthur Owen Lomer, and suspect that his name changed. Your Arthur Owen Purkins b 1853 Marylebone, came to my attention and the more I look at the family - the more I believe he may have changed his name to Lomer.
You state that William's second wife's maiden name was Lomer. Could I ask if this is documented? If so, it may be another dot on the connection line.
Thanks!
