Thanks for your interesting reply, Mary. Actually, I would say it's not at all unusual in the IOM to find husband and wife's families to be connected - I have several instances in my own family, ancient and modern!

I would be very interested to hear more about Robert Collister Moore as all I have is his birth from Brian's website and the 1901 census entry. As I said above, his mother Robina Catherine (Collister) Moore was the sister of my great grandfather Thomas Collister. Thomas's first son was called Robert Collister.
