The first of the Clemos

Not really. I'm sure that the Clemos go back a long way, but for the purposes of this story, there is an entry in the St Erth register of marriages:

Wedding on 22-Aug 1865
William John Clemo aged 23 bachelor occupation mariner of Hayle in St Erth, father John, occupation mason, married
Elizabeth Richards Champion aged 24 spinster of Carnisers, St Erth, father Thomas occupation labourer. Witnesses R H Champion, Ann Champion

After much searching the Phillack 1871 Census I discovered this entry here

Folio 44 Page 5
26,Cross Street,1,William Jno Clemo,Head,M,28,,Mariner,St Columb Cornwall,,
,,,Elizabeth Clemo,Wife,M,,29,,St Erth Cornwall,,
,,,William Hy Clemo,Son,,1,,,Phillack Cornwall,,


So is this the Clemo family that Elizabeth Henrietta Hayes married into?
Sadly, no. She married a Charles Clemo, father also Charles, in St Erth in 1895

Wedding 1895
Charles Clemo aged 23 bachelor occupation engineer of St Erth, father Charles Clemo, a seaman,
Married
Elizabeth Henrietta Trevaskis Hayes aged 24spinster of St Erth father James Henry Hayes, occupation- smith. Witnesses Mary Amelia Hayes ,J.H. Hayes

So Wilhelmina didn't marry a seaman after all, and neither did her daughter Elizabeth, contrary to family tradition.
Ah well, back to the drawing board.
