Brothers Marrying Sisters

 

Thanks to all the work I've been able to do with DNA matches this month, I had already outlined several descendants of the next son of Lyman Jackson. Researching the descendants of David Bardsley Jackson, the eighth son and ninth child of Lyman and Deidama, became a curiosity owing to one point: like two of his brothers, he married a Hendryx. And with that choice, he also married his first cousin.

David Jackson's wife Lucy Hendryx was daughter of Mehitabel Dunham Hendryx, who in turn was sister of David's mother Deidama. To complicate matters, David's older brother Michael had married Lucy's sister Ruth, and we've already learned that David's brother Abner had also married one of the Hendryx sisters, Tryphosa. 

At a closer relationship level, I imagine such marriage arrangements would make for some interesting DNA matches, but in my mother-in-law's case, though she does have several instances of pedigree collapse in her heritage, that is not the case for this Jackson line. Her direct line Jackson ancestor, John Jay Jackson, married someone outside this family connection along the Jacksons' migration route from Vermont through upstate New York to Erie County, Pennsylvania.

Still, it is interesting to realize that descendants of both David and Abner show up in our Jackson DNA matches, but not any descendants of Michael—yet. However, I wouldn't be surprised if patient waiting and diligent checking over time might yield some new matches to descendants of all the Jackson children.
