Hi

I know this is years after you first posted but they had 3 children (from stuff I have found)
Robina Challinor Edwards born 08 April.1883
David Challinor Edwards born abt 1885
Evelyn Challinor Edwards born 10 June 1892

I'm researching Challinor but no connection to Robina. I just keep everything I find on the name.

Best of luck with your research.
