My linage is as follows:

5GGP: Edward Blwett(1700-1747)of Gwithian, Cornwall, & Ann Cock(same)(1702-1747)--->
4GGP: John Bluett of Tywardneath, Cornwall,(1740-1825)& Elizabeth Foote(same)(1740-1782)-->
3GGP: John Bluett of Tywardneath, Cornwall,(1768-1838) & Anne Warne(1776-1843)---->
2GGP: John Bluettof tywardthneath, Cornwall,(1802-1852) & Honour Rodda(1804-1863).
John and Honour married in Philllack, Cornwall in 1924 and emmigrated to US in 1833.
Being miners, they first settled in Pennyslyania and later went to California USA

Being a desendant of the Bluets of Cornwall I have been unable to connect them to the more well-known Bluett of Holcombe Rogus. I have read there is a commection but dont know if it can be docuemented.

Any Suggestions
