Well, I've had an interesting couple of weeks. After uploading my Plockhoy book I did a routine Google search on Plockhoy, something I hadn't done for a while, and found a Dutch guy doing his Ph.D. thesis on him. He had new info; it turns out that Plockhoy was married to a woman who remained in Holland and never traveled to Delaware, his son was a tinsmith and not a stocking knitter, and people who I thought were his siblings really weren't.
So I did a lot of thinking. Do I rewrite it completely? Do I change the names? I decided upon the latter, not wanting the facts to get in the way of a good story. I now say in the Preface that it is "loosely based" on the Plockhoy settlement. Does the DRM allow a Kindle user to re-download the corrected version? Only six people have bought it so far, so it's not a huge problem. I did acknowledge the Dutch guy; he was very nice, and his thesis is very interesting.
