Hello Joyce, I have done quite a lot of research on the family Trollinger and some on the Trolingers. I have a line that starts with Adam Trolinger in N.C. and it goes through several generations. If you send me what you have as far back as you can, I will check that against my "stuff". If this doesn't work I can refer you to a couple of researchers whom have researched the one "L" line. I am in contacted with quite a few these people. They have been very helpful.
Good to hear from you, Ed. T.
My mail address is: Edward Trollinger 208 Ruth Street Rockwell, N.C. 28138
