There are scads of Joseph Pack's descendants who live in and around Paxville. After all, with 12 children, how could there not be tons of us. There might have been an old family home at one time, but it's long gone by now. As far as Joseph and Louisa's graves, they are probably buried in the old section of the Paxville cemetery. In that section, the graves had wooden markers which have been gone for generations. However, there is a marker that does have Joseph's name on it. Where do you live, if you don't mind my asking?
I'm descended from Alexander's sister, Mary, who married Daniel Kelly. Looking forward to hearing more from you.
