Hi Greg,
I'm Jarvis-2158, look at my tree and my first wife is a Schuitema. My father-in-law was born in MusselKanaal, and lived in De Vetstukken, near Groningen. He, Jurjen, spoke Groens. He used to say that an ancestor of his was also a painter, Etsko Schuitema. I wonder if your ancestor, the painter, was part of the same 'group' of painters. Etsko was a still life painter (flowers in vases etc) as understand it. Perhaps there is a family connection somewhere as well? Rob Jarvis
