Find Living Relatives

I don't know how you would find out if they had any children. I would imagine that because they didn't move to USA until 1950 that any children would have been born in British Columbia but online birth records there only go up to 1903.

To Margee and +++DetEcTive+++ thanks folks for the great info.
(found Florence's address on Googl street view !). That brings Florence and John into America. Is there anywhere I can contact to find out if they had children?

Possibly John's death?

Have you looked to see if anyone on genes has any of your relatives in their tree on here?

My name is David Wright and I've traced my family tree of George Rigby Lowe back to VancouverCanada and his daughter Florence Miriam Lowe marrying John Leigh Thomson in Cloverdale Vancouver in 1932. Has anyone any idea how I can find more upto date details, like wether they had children and grandchildren and so on?

Help.

Cheers.
