He was one of five children noted in the will filed by his father in June 1690.
By 1683, he had married Barbara Groesbeck. Over the next two decades, their eight children were baptized in the Albany Dutch church where he was a member, frequent baptism sponsor, and one-time churchmaster.
Nominally a shoemaker, he set up his shop in his home in the second ward where he served as constable, assessor, and juror. By 1697, he was a rising merchant and his Pearl Street home an Albany landmark. In 1711, he was chosen assistant alderman for the second ward and served for several years. He also served in an Albany company of the county militia.
Although still a prominent resident, after 1720, he seems to have retired from public life.
Gysbert Marselis died in June 1740 and was buried from the Dutch church.
