These Blackburn girls, to further complicate the family connections, were orphaned nieces of Mrs. ‘Judge Bushrod’ Washington’s, so Mrs. Washington’s two orphaned nieces married her husband’s two orphaned nephews. 
These Blackburn girls and their other sisters were very strong members of the Episcopal Church in its period of revival. The Episcopal Church had gone into a decline after the Revolution because it had seemed associated with the established church of the colonial government, and therefore with the colonial government and Britain. But it began to come back, particularly under the leadership of Bishop William Meade. Some people became very enthusiastic lay supporters, and the Blackburn women were among them to the extent that Bishop Meade's classic book "Old Churches, Ministers and Families of Virginia," especially refers to these Blackburn girls as 'the first fruits and some of the most valuable fruits of my early ministry.' The lady whose husband built Claymont kept a diary which, though I've never seen it, I am told is nothing but one long series of religious and pious reflections, and has none of the historic and genealogical material that we would like to find in a diary.
