Reynolds, Barrett & O'Connor??

Looking for info on John Reynolds 1828-1921 whose last home was outside of Cong, property owned by the Coyne family. He was last married to Honor Barret who immigrated to US in 1930 and died shortly thereafter. He is buried on the Hill of Doon near Castle Kirk. He had a first wife, possibly Anne O'Connor from County Cavan but I have nothing to really substantiate this. I would love to find any information on any of the above as this is a dead end for me.  Thank you!
