I have traced my Erasmus line back to my 3x Great Grandfather David ERASMUS who married Mary WATKINS in Bedwelty, Monmouthshire, Wales on 1 August 1820. I do not know when or where he was born. However, as a result of taking the Ancestry DNA test I have established that almost certainly I share a common ancestor with Pieter ERASMUS ("Den Deen") who went to the Cape, South Africa in about 1693 and also with Thomas ERASMUS who had children in Pembrey, Carmarthenshire, Wales from 1708 to 1720. It is thought that Pieter probably came from the Netherlands or Denmark, but I have seen no documentary evidence (yet) to substantiate this. I am looking to establish contact with anyone with the ERASMUS surname (or with Erasmus ancestry) who has also taken a DNA test to see if we also match.
