Alice, Let me make this easy on me and just copy what I sent someone else.If you are still on here, then you can contact me, I have seen others looking for William D. spelled differently.
I have seen Dorsett, so along with all the other variations of the name, yours too could be part of D'Arce-English or D'Arcy-French related to Darce who is related back to Edward III, King of England.Mine were known as Dorsey, from Edward the Immigrant, he is called.
I have part of that ancestory.I have a Mary E. Smith b 1802 d/o William Smith m Silas Dorsey.These are my ggg-grandparents.One of their daughters, Rhoda Dorsey b 1826 m Thomas Chandler Woolley/Willey/Wooley/Wade/Ware/Ward/Wharton/Wylie/Woolege/Woodworth/Woodward/Wooldridge/Woodruff/etc many more AKA's.
Your Murphy, I recently learned could also be Marrs (mine)/Mars/Myers/Morrow/Meers/Mears/Mead/Maier/Meier/Meek/etc AKA's.I have a James Marrs b 1809 s/o William and Mary McClure, Marrs.
Spearin aks so many ways and also in my family.Those I havent't been able to trace as there are so many variations.
Other surnames you have that are on a list my mother gave me of only surnames are: Russell, Burgess, DAughtery/DOughtery, Anderson.I didn't noticed Neal or Robinson, or even a Shafer/Shaffer/Haffer/Shaver/Scheaffer/etc.I have more names that get me distracted than I will ever find, but am beginning to find some may have been in Canada for awhile or Wales, NS, ?That's just a few to perk your interest, let me know if you think we might have something here.
