I didn't realize John and Susan had another son William until now. I just did a quick search and found them in Evesham, Burlington county (1860) but the name in the census is Wonderland instead of Wonderlin. Thanks for the tip off. I will let you know if I find anything else. Although it is strange that William does not appear in the 1850 Census with the rest of the family when he would have been 11. I wonder if there are other siblings I am missing. So far I just have George, Charles and now William with Charles being a bit younger than George and William.
