The only info I have has to do with the ancestry of Elizabeth Stiles and is what is available on the internet and in genealogy resources in NJ public libraries and the Burlington County Historical Society. For example one website (http://hollingsheadancestors.blogspot.com/)gives Elizabeth's male line as Reuben, Ephraim, Robert Jr. and Robert Sr. There is a chapter on this Stiles family in a book on genealogies of PA families - I don't remember the title but it is common in NJ and PA libraries.
Interestingly, that website reports Elizabeth's sister Sarah Stiles married Samuel Sexton and moved to OH and IL as did Elizabeth.
This Stiles family of NJ and Philadelphia is not the Stiles family of CN, some of whom moved to NJ to complicate the life of genealogists.
