I do not believe such a connection is "likely." And, the chance that aepi would have a dance in that barn is zilch imo.
I disagree, from personal knowledge. Jewish people play a game called "Jewish geography", finding other Jews they know in common. It's unlikely that there are any Jews living in Martinsville, but not surprising that if there actually is a Jewish family there, that they've developed a connection to others in B'ton.
Also, as for the barn location being used for a party, it is very common these days to use an odd facility for a party. I used to work in the arts/cultural world, and they loved to host parties in unusual, but cool, spots. I actually had to work a party that was held in a brand new, high-end mausoleum. That the AEPis would have a barn dance in an actual barn surprises me not in the least. It is a straight shot up Hwy 37. No big deal.
FWIW, I attended an AEPi formal party a million years ago at the hotel in French Lick Springs, IN, where they filmed the movie, The Shining.
