Jonathan & Martha [McClain] Sanderlin had 7 children. Mary, Joseph,Joshua,Jonathan,Rebecca,Asa, and Emeline. I descend from Jonathan's branch. The "U" was put in our name about 100 years ago. We have a family Bible which dates to 1850. I do have more info on the Salem County ,N.J. Sanderlin's...mainly in the 1800's and some earlier.
