Dear Liz, You must give dates for the Kestner men you are mentioning.I have not seen any information about Henry, Jonas, or Leonard.What census records, court records, wills, etc. can information about them be found?
The forname Phillip was carried down in the Kestner/Kistner family, (definitely more than one Phillip Kestner). So a lot of care has to be taken not to confuse them.
Would you please elaborate on the wife of the John Kestner who is said to be the father of Henry, Leonard and Jonas?
