Hi
Frederick(1)and Catherine's son, also Frederick John Griffin Rainbow(2) married Sarah Emma Proctor in 1891 and had 4 Children. They were married in Coventry where their first child Dorothy was born (1893), next was another Frederick John Griffin Rainbow(3)- born in Southsea, Hants in 1895. I believe the older Frederick and Catherine stayed in the Portsmouth area while Frederick 2 and family moved to Barnstaple, Devon. They had another 2 boys Leonard (1896) and Gordon(1899). I believe Sarah died, I'm not sure whether it was before or after they moved to Newcastle upon Tyne. My husband is Leonard's youngest son. I've done quite a lot of research and this is the first time I've come across anyone from 'our branch'.There was another Frederick
John Grifffin Rainbow who died about 10 years ago in Newcastle, I assume he was Frederick 3's son. Hope this helps
