Hi, Barbara Reed. My great-grandmother Rachel Browning Purdum was a sister of your great-great-grandfather Joshua Hinkle Purdum, which makes us 3rd cousins once removed. I don't know of any specifically Purdum reunions, but over the last several years a Norwood Reunion has primarily attracted persons with a family tree interest whether directly descended from Norwoods or not, and pretty much everyone with ancestors in the area is interrelated anyway. It's usually in April, let me know if your're interested and possibly in the area. I'm currently working on Richard Cheney, immigrant -- the line back would be Joshua Hinkle Purdum --> Jemima King, wife of John Lewis Purdum --> John Duckett King --> Rebecca Duckett, wife of Edward King --> John Duckett --> Charity Jacob, wife of Richard Duckett --> Anne Cheney, wife of John Jacob --> Richard Cheney. He showed up in Maryland about 1652, before that it's blank.
