My great-great grandmother was Mary Catherine Dockery b.19 Nov 1827 in TN. Siblings that I know of: a brother,Linsey Miller Dockery, two sisters, Lucinda and Martha Dockery. All born in Tennessee. I have the father's name as being John Dockery. On an 1880 Census states Linsey Dockery b. abt.1832. Father from South Carolina and mother from Alabama. Is there any relation to the Earl Brown and Frances(maiden Unknown for now)Dockery's? As they too travelled from TN. to Texas.
