Mike Cumpston at cumpston@grandecom.net wrote to me on 6th September 2009 about his family.

Subject: Cumpston -Ireland

'We seem able to trace our branch to a James Cumpston of Belfast Ireland born about 1800. My great grand father, Henry Cumpston was born in 1830 came to the United States, Married Ellen Mclockland (sic)- also from Ireland. In or about 1970, he settled in Navarro County Texas.

These Cumpstons began as Catholics with no apparent knowlege of English ancestry. I was told that Henry converted to Methodism becasue their was no Catholic presence in the region. I later found out this was not true as a priest arrived to administer extreme unction. Years before, Henry had apparently been tossed out of the Catholic Church and Ellen met the priest at the door and most colorfully told him to get off the property.

Henry and Ellen's issue include, James Henry, Fredrick Bernard, William Frank (Cumpstons) and others who tended to inter-marry with the the Scottish Campbells and Furras of the area.'
