The reason you may be having trouble tracing here is that there was possibly a name change. Most English records lists the name as Bollyng. Also, there are some Bolden's, Boulden's in this area also. There is a huge amount of info in English records, but some of these records are thousands of years old. I'm sure public access is minimal. Hopefully, this will help in your search. By the way the Bollyng means in english "to tipple", which is actually a reference to a brewer.
