Thank you keyboard 86! I have most of that (sorry!) but need to go backwards to try to link these Cosway's (my d-I-laws family) to the Sir WR Cosway branch. I'm thinking he may be a brother of her ancestor somewhere along the line. Both families originate in Tiverton Devon so although this will take some time I'm cautiously optimistic! and quite happy to be proved there is no link either! Joys of genies 

Good fun this, any idea of where George snr is in 1851/61?

PS Appreciate you have all I have given, but not only for me, but others searching, need to see dates of birth etc!
