Hi there Avro,
I have a fair amount of information on your (and other) Schilps to whom you are related. Including your Johann's birth in Borgentreich, Westfalen, Prussia, his parents, Franz Schilpp and Carlina Hartmann's marriage and their children.
I have John's wife Christian/Christina HIBBELER's birth, parents and siblings too, this family were also from Westfalen, Prussia.
I'm trying to work out a positive link to Frederick Schilp (Westfalen) who turns up in Greenock (from West Ham) at exactly the same time as John. They are not brothers but are perhaps cousins.
Frederick's parents were Joseph Schilp and Sophia Eikermann.
I'm not related I was just doing a wee favour for the wife of one of John's descendants.
