He was a young Englishman from London [Editorial note: later generations of Sixberry/Sigsbee/etc. researchers have questioned this]; coming to Schenectady he married in 1699 Pietertje, daughter of Jan Janse Joncker and settled upon the easterly portion of the First flat, called Hazlenut flat. Ten years later, in 1709, being a soldier at Fort Nicholson [Fort Edward] and sick, he made a will giving his property to his wife and four children, Johannes, Wilhelmus, Cornelis and Mary.
His son Wilhelmus settled in Maquaasland about 1720. (145-4)
