Hi there,
How exciting

to finally find family still back in South Shields!
Your Grandfather Thomas M. Hansen was my mother's first cousin.
Your gt grandmother Harriet Blanch Mitchelmore was my grandfather's sister.
My branch of the family came to New Zealand in 1926, my Grandfather lost contact with his sisters Blanch, Ethel and Annie, and when he returned to UK for a visit in 1958 it came as a bit of a shock as they thought he had died!
I have done a lot of research into our family and would be happy to share my info.
I will post a private message with contact details.
