For the last three months I've been working a lot on the Sandercock families, most of which seem to originate in eastern Cornwall and western Devon in England. I've been trying to link all the ones I find into families. My own branch come from Cardinham in Cornwall, and Ive traced them back to the marriage of William Sandercock to Mary Verran in 1729.
Now I'm trying to bring all Sandercock researchers together, and there is a Sandercock family forum
where researchers can compare notes and exchange information.
