I've compiled a bit of info about a family of Hardesters living in Baltimore from the late 1700s into the mid-1800s. Father was Benjamin (~1765-1842) a sailmaker in Fells Point; mother was Ellen. They had 8 children, including Amelia and Elizabeth (and maybe Jacob and John). If this sounds like your family, feel free to contact me and I'd be happy to share what I know about them.
