Do you have a connection to Aaron Wonderlin who married Hannah Rockhill?
I was recently at the Burlington County Historical Society researching my GG Grandfather James Wonderland. I have reason to believe he was the son of Peter Wonderland, not yet proven. Peter was the son of John Wonderland and Amy Pitman, proven. I found something that might be of interest to you.
This was recorded in the Registry of Baptisms By the Methodist Elders and Deacons of the New Mills Circuit 1788-1789. The New Mills Circuit operated out of Pemberton, Burlington County, New Jersey.
June ye 15th 1789 Baptized by John McCafky Deacon
Aron Wonderly son of John Wonderly
I have seen the Wonderland/Wonderlin name interchanged with Wonderly. This sure looks like the baptism of Aaron.
