MAHALALEEL SHACKLE was in the organization of North District 
Association, in 1802.  From whence he came to Kentucky is unknown.  He 
was an elderly man of very moderate gifts, it appears.  He was the 
minister at Locust Creek church, a few years.  But when David Barrow was 
expelled from the Association, in 1806, on account of his Emancipation 
principles, Mr. Shackle adhered to his party, and became a member of 
Licking Locust church, and of the Association bearing that name.  He 
continued to preach among the Emancipationists to a good old age.
