This particular " Joseph " appears to have been born in England around 1630 ( as best we know ) as it is referenced that he had a Baptist Church Certificate from Leicester; hence one cannot assume he was born in Newton, Mass. I too am stumped as to his parents and other lineage prior to 1630. The search must continue in England in Church records, etc. in and around Leicester and maybe Sussex. Kindly advise if anyone is lucky in this pursuit.
