Hello,
The John Bluett(b:1768)that you mentioned is my G-G-G-Grandfather. He and Anne Warne had a son John Bluett(b:1803) and he married Honoura Rodda. Their son was Joseph Thomas Bluett(b:1847) and he married Elizabeth Joyce Abernathy. Their youngest daughter was Daisy Bluett, my grandmother. She married Louis McElvarr. They had 5 children and my dad was the youngest.
Joseph & Elizabeth lived in New York, Cenral PA early on and later moved to Phila Area and died here.I personally dodnt know any of them but do know some family stories.
As far as I can tell it was Joseph's brother that left PA and moved west. They settled in Iowa, Nebraska, Veveda,& Calif.
Hope this answers some questions.
Steve
