Not important but there are 3 breeds mixed up here.
Friesian (not gul), a dutch breed
Groningen gul, also a dutch breed
East-friesian gul, a precursor breed to the groningen gul but from across the border with Germany
All come in autosomal barred pattern. Friesians have more color options.
Friesland is a northern dutch province to the west of the province Groningen, which is at our eastern border with Germany.
