Okay . . . I will start at the bottom of your queries. I have your Philbert Wright, however I have him as Philburd Wright b. 29 Mar 1768 in Rowan county, NC and d. 31 Jul 1855 in Washington county, IN. He had 2 wives. 1st was Mary Molly Sears and the 2nd was Elizabeth Deven. Philburd's siblings were Benjamin, Peter, Richard Jr., John, William R., Evans C. and Amos Sr. He was the son of Richard Sr. b. abt 1730, d. 3 Sep 1784 all in Rowan county, NC. You mentioned that Phibert and Peter were nephews of William. William's brother is indeed Richard Sr. however I don't have any info on this William other than him being b. abt 1719 in Surry county, NC. I do have a Rachel that might fit and too many John's but not one who died before 13 Jul 1825. Not sure if this will help you or not.
