Red herring No 1 coming up......Whilst searching (vainly) for a James Williams who is alleged to have een a missionary in China I came across following.......James Toy Williams Alalbama Missionary.....just 'google' James Toy Williams Missionary China and log onto the book 'Taking Christianity to China:
Hi, I can not help with date of marriage between John Williams & Harriet Trevaskis but the bdm index is " July - Sept 1894 Redruth 5c 280" The 1901 Census if any use:
"RG13/2243 folio 86 page 14 ed 5 sch 98 ,14 Centenary Street,Camborne. John Williams,head, mar, 59, Tin Dresser, worker, born Tregony Harriet Williams,wife, mar, 41,born St Erth William J Trevaskis, step son, single, 16, born St Erth John Williams, son, 11, born Camborne Harriet Williams, dau, 5, born Camborne".
I have been working on the Trevaskis line for my cousin & have the same date for Richard & Harriet marriage. Her dob was 7 Jan 1860 & bapt 20 July 1860 dau of William Henry & Selina Trevarthen (taken from Genuki- St Erth & OPC).
