They were Presbyterian. John's profession was a farmer and they came with a servant named Elizabeth Boyd. I forgot to mention that David McCandless, a Sadler, who was 18 also arrived with them. His age makes him a bit too old to have been the son of John and Martha McCandless nee Hanson and we suspect he might be a nephew to John.
I have some info on the Hansons, John's wife if that helps, but I don't have much on the McCandless side. We might be off on Macosquin... we thought they came from that area because that was the location of Martha's father, William Hanson.
