Some of the best blogs seem to peter out quickly. I suspect it's because the author pours huge amounts of time and work to each post. Once life gets in the way, continuing may no longer seem worthwhile. I suspect that's what happened with Parkman Genealogy.
Designed to trace the American version of the Parkman family, the blog ran for only a few posts. But what is there offers great material for new researchers. You can study the Parkman Coat of Arms, review the history of the first Parkman immigrant, even enjoy pictures of their shoes. Have fun!
