I am trying to clarify whether I have a link to Peter Brickey (1715-1786) through a daughter Dorcus (1748 - 1786?), who is mentioned in his will.

She married James Garner (1792-1796). They had a son Fouchee Garner (1780-1863) that I am descended from.

The info on the children of Peter and Winifred is confusing.
Most of the posters on this board researching that family seem to be descended from the older boys. Any info on Dorcus would be greatly appreciated.
