Mr. Charles Baker is quite correct, I have been to the grave of Andrew Robeson D 1720 and have photos, his wife was Maria Helm, daughter of Israel Helm (I have copy of the will). She is buried in Old Sweds Church in Philadelphia, I have photos and would send them if necessary.
Permit me to jump into this conversation --
I think where the great confusion lies is the adding of Sr. Jr. and III to the names of Andrew Robeson. Since joining this group this is the first time I have ever seen it used.
I came across some excellent books: I will cite one
Colonial Records of the Swedish Churches in Pennsylvania Vol 3
on page 110 it states "His daughter Magdalen (Rudman) married Andrew Robeson, Jr. at Gloria Dei Church on 21 August 1718."
