I'm researching Alvah & Sarah Marston of Durham, Cumberland Co., ME. I have their children, including Vesta Adelaide (Marston) McNitt. This family left Maine and went to Pennsylvania where they lived in Hartley Twp., Union Co., PA. I'm especially looking for the parents of Alvah, b. ca. 1806 in Maine and Sarah Ann (maiden name unknown) b. ca. 1815 in Maine. I'm willing to share.
