Cornish Surname Index
1,114 Cornish surnames, parishes and dates – 11th edition, March 1997
About the index
The Cornish Surname Index was a shared list of the Cornish surnames that family historians around the world were researching. Each entry gives the surname, the area of Cornwall the family came from, the dates being researched and the researcher. This is the 11th edition, dated 11 March 1997, when the index had grown from 910 to 1,103 names (1,114 entries appear in the list itself). It was circulated on the GENUKI and ROOTS-L mailing lists and was hosted on Ian Richards’ Cornwall Online site.
Nearly thirty years on, it is still a useful finding aid: it shows which surnames were found in which parishes, and points you towards other people who have worked on the same families. Search for your surname below, or jump to a letter.
