The first
VanCise, VanSice, VanSise (current known variations - also used
Van Syce,
Van Size,
Van Sysen,
Van Syssen, etc.)stated that he was born in Middleburg, in the
Province of Zeeland, the Netherlands [Holland]
It's possible that the name was a "revival of a "dormant" family name, so common among New Netherlanders. In Holland the name van Sysen existed before the year 1650."
I have also seen
Province of Groningen, Netherlands) and one other location that I can't locate right now.
I have no close, straight line, male descendants to help you out but would love to hear if you find someone to participate and what you find out.
