There was a Bogstown in the Braid area. In the book Presbyterianism in Buckna 1756 to 1992, it details the original boundaries of the parish/church. Within same it states:
"...from Tecloy Hill to Bogstown; road from Bogstown, through Loughconnelly, to Ballymena Road;..."
and a hand drawn, rough map also clearly shows Bogstown within the boundary line.
There were certainly folks of the Crawford name in the Loughconnelly area in mid 1800s too, with the forenames Thomas, Mrs., Robert and William recorded together in an 1862 Communicants list for Buckna church. I shall try and get some time to check for other mentions of the surname in the book and update this post accordingly.
If you PM me with your email address, I will be happy to send you a jpeg picture of a partial OS map with Bogstown clearly recorded, which will enable you to compare it with more modern maps.
