A couple months ago, HSP lauched a new blog, Roots and Branches, to help highlight HSP's genealogy and family history resources. I just wrote a post for the blog on a new collection we receivedly received, the Vauclain family papers and genealogical research materials (Collection 3666). This collection is a fantastic resource for genealogists as well as those researching Philadelphia's Vauclain family.
Roots and Branches already has some great posts and new content will be uploaded monthly, so be sure to check back in for more genealogical stories from HSP!
