Can't help you with Ince/Inch, but can make Ince suggestions. Ince appeared to connect with my Dale tree, but turned out to be a big red herring, due to an amzing number of coincidences. It led me however to mail a person in Australia with Dale stuff of hers, not mine. She is connected with Ince, and suggested I looke at the 'Worksworth' Derbishire site. It has 300 years of genealogical date on line, all to do with Derbys. An Ince from Derbys. has written a book on pedigrees, and there is a heap of Ince information on line there. Maybe this will be of use to you. If it isn't, then it is an interesting site to browse anyway.
As usual, I can't remember the site address, but using my favourite of Google and searching Wirksworth will take you there. Susanne.
