This took a little work, but I have you worked into the tree:
John Ping (1740-1823) & Lydia Bradley
- Robert O Ping (1785-1858) & Jemima Smith
-- William Ping (1808-1867) & Elizabeth Reid
--- Thomas B Ping (1831-1882) & Mary E Keefe
---- Thomas Andrew Ping (1862-1903) & Laura Alice Bright
----- Frank Terry Ping (1889-?) & Lottie Myrtle Dowers
------ Leonard Ping (1909-?) & Nell Pierce
------- Thomas Theodore Ping (1931-2013) & Annie Jean Ward
-------- Donna Ping
Oddly enough, you're the second "Donna Ping" we have on the site, out of a total of six in the country that I know of.
There aren't a lot of John Ping's descendants in North Carolina, for some reason; I'm only aware of one other family group
in the state that fits in the Ping family tree.
