I have Samuel Allen a son of Jospeh Allen, who died in Spottsylvania Co., Va. in 1782. Other children were Winifred, Anner, Rachel, Mary, Susannah,Barbary (Barbara?), and Joseph. Joseph Allen (sr.) was son of Erasmus Allen who was born abt. 1671 and with wife Dinah Waggener had in addition to Joseph, Erasmus and Rachel. I do not know where Erasmus lived or died.
Samuel Allen was married to Mary McAllister dau. of Wm. McAllister and Elizabeth Garland of Louisa Co., Va. Both Samuel and Mary lived in Louisa Co., Va. I am not familiar with their being from Essex Co. I will be happy to exchange any info I have.
