Dear Joan,
Perhaps I can help.
My paternal grandmother was born Hilda Leworthy and grew up in the
Swansea area. She must have been born about 1890 or a little before. I havn't done much research on her side of the family except that all Leworthys originally come from the region about the village of Leworthy in
Devon. The only other Leworthy I can find in the area in the 19th C is John Leworthy aged 22 in 1851 living at 14 Maddoc Street,
Swansea (census). He lived with a master shoemaker called
Jones together with another (third) shoemaker called William Peddler. All of them where born at various small villages/towns near Leworthy. And the age and birthplace of the youngest of the
Jones children suggests that they had all moved to South
Wales between 1847 and 1849.
I haven't checked later censusses so I don't know whether Jon Leworthy had male children who could have been the father to my Hilda Leworthy (married name
Tribe).
I think this might have interest if your family has been in the Hereford/South
Wales area for a very long time.
