"Michael and Sophie inherited Sophie's Father's Inn in Pleasant Mills, New Jersey and they renamed it to Lafayette Tavern.."
What is your source for this? FYI, the Wharton Ledgers do not mention Gaurotte by name. I'm going to the State archives today to view the entry in the ledgers. I'll report back later today.
Its called rounding it down using repetitive logic based on facts. Quakers were not allowed to own or operate taverns and it is a fact that garoutte was a catholic and he married a quakeress and they both converted to methodists. Its also a fact that he owned and operated a tavern that was formerly just an inn. Clearly this inn belonged to his wifes father James the quaker before it belonged to Garoutte. And according to the Budd's Father's Notes on The Wharton Ledgers Garoutte's Tavern was named The LaFayette. Additional proof of Garoutte operating an Inn and Tavern and a Stageline is found in that newspaper publication dated 1844 detailing the history of stagelines from 1700s to mid 1800s and more proof is found in the book iron in the pines which details Garoutte's stageline and Tavern.
I was only giving an example on how to legally prove legitimate descent from an ancestor.
