Great Grandfather Was Born In Blaenavon In 1865

A Memory of Blaenavon.

I have been doing research on my family tree and found my greatgrandfather William G. Godfrey, was born 1865 in Blaenavon and lived on 48 King Street, in the 1880's. He was a minor and immigrated to the USA in 1889 with his dad John and mother Sarah. They had a lot of kids. Just wondering if there is still family over there.
