I believe this gentleman came to Pennsylvania from the slate quarrying area of North west Wales, possibly along with brothers Richard (Owens ? ) Prichard b 1826 , William Prichard b 1829 and Robert Prichard 1832.
A while ago, I thought I had found him on the 1870 census in Lehigh county, married with a wife Mary ( b Wales 1848) , and a daughter , whose name was transcribed as 'Lovia' , b 1869. (I think that this is a mis-transcription of Laura, which would be his mother's name) . I can find no other trace of any one of the four brothers. Does anyone else have any idea what happened to them , please ?
