(1) 11 Aug 1611 Saint Martin On Looe Bay, Cornwall, 30 miles East from Saint Just In Roseland.
(2) 15 Feb 1626 East Newlyn, Cornwall, 12 miles North from Saint Just In Roseland.
I found the reference, you mentioned, to William & Ann wedding in 1646. Unfortunately this is the only Andrew/Androus wedding in the parish during the 17th Century. However, I have found reference to a few other Lamertons who were married after Ann. I can happily send dates/names for these.
The Parish christening register only goes back to 1727, and there are no relevant grave stones in the cemetery.
I had a quick look at the wills website: http://www.nationalarchives.gov.uk/documentsonline/wills.asp but couldn't really find anything relevant. Maybe you could take a more thorough look.
Susan Old, the Online Parish Clerk for St Columb Major supplied a wonderful response to a query on ColonTippett's baptism. She added three generations back, for someone who had been a very murky figure to us. Also thanks to Graham Warmington, OPC St Gluvias, Penryn, see above.
