My dad was Kenneth Merritt "Puntenin" Hennessey of Mankato, MN; his dad was Francis "Pete" Jerome Hennessey, also from Mankato; his dad was John Patrick Hennessey, born in Ireland but moved to Pennsylvania. I think (no supporting documents) that his dad was Patrick Hennessey married to Ellen Russell. The timeline suggests the Patrick Hennessey mentioned by Leah Chaillet-Hines may be the same Patrick I suspect because they both had daughters named Mary. What is your take?
