Hi Sailerch I am a Sowden & have a tree back into the mid 1700s.
Just per chance there is an overlap my crew were St Cleer, Liskeard, Bodmin & Camelford based.
About to make another voyage of discover over there & interested in any Sowden data.
Have you googled James Sowden Bodmin jail. I have not identified a line to him, but an interesting character insight of our name.
