Have you ever been to Holland? If so, did you find any traces of your ancestors? An ancestral home maybe, or the church they attended? Maybe you can show us a photo?
My photo is from my great-grandparents (and later my grandparents) home. I took it in 2006. The ivy from my grandparents' time was gone, but otherwise not much changed, at least not on the outside.
If you did not look for ancestors when you were in Holland, then what did you do? Visit tulips and windmills, or the Dutch masterpieces at the Rijksmuseum?
