By sheer chance I decided to Google my grandfather's name tonight... and found your post. Erastus Irwin Mallory was my great-grandfather. His son, my grandfather, was also named Erastus Irwin Mallory. I do not have an obituary for my great-grandfather, but have not looked back through all the family's records for several years. I'm more intrigued by what you might know about the family records preceeding Joseph. I've never had a definitive tree beyond him, and have trusted to family hearsay that Joseph came from Virginia. Feel free to contact me by email at firstname.lastname@example.org.
