Thanks Uglybloke,
Thomas was married first (no record) to Sarah Knox and was living in Tranmere in the 1871 census with his daughters Mary E (3) and Sarah (4m) who was my great grandmother, I know this because I have her birth cert. I traced him back living with his father John and his mother Mary where he is listed as being born in Llangollen. In the 1881 census he is living with Priscilla (nee Cutler and then Summers - she was a widow), her son Arthur (who took his surname), several other children and another mother and son (husband is away at sea), but has put his birthplace down as Seacombe (Birkenhead). I can even show you a picture of the house they all lived in!
Thomas moved to Tranmere when he was very young, so I suppose he thought he was born there by this time. It is just his birth that I can't find, it is listed variously as 1839 or 1841. In the 1841 census, his age is given as 1 yrs.
Thanks again for all your help, I was not sure of the deaths, but you have confirmed them for me.
