Welp I was wrong in a big way 🤣 It seems that Jack and Meg were not related but in actuality, but instead were a married couple. Jack took Meg’s last name and, I’m assuming to keep the public eye away, presented themselves as siblings.

Been thinking of the Bach siblings.

Johann Sebastian Bach.. was a member of a remarkable family of musicians who were proud of their achievements, and about 1735 he drafted a genealogy, Ursprung der musicalisch-Bachischen Familie (“Origin of the Musical Bach Family”), in which he traced his ancestry back to his great-great-grandfather Veit Bach, a Lutheran baker (or miller) who late in the 16th century was driven from Hungary to Wechmar in Thuringia, a historic region of Germany, by religious persecution and died in 1619. There were Bachs in the area before then, and it may be that, when Veit moved to Wechmar, he was returning to his birthplace. He used to take his cittern to the mill and play it while the mill was grinding. Johann Sebastian remarked, “A pretty noise they must have made together! However, he learnt to keep time, and this apparently was the beginning of music in our family.”

Until the birth of Johann Sebastian, his was the least distinguished branch of the family; some of its members, such as Johann Christoph and Johann Ludwig, had been competent practical musicians but not composers. In later days the most important musicians in the family were Johann Sebastian’s sons—Wilhelm Friedemann, Carl Philipp Emanuel, and Johann Christian (the “English Bach”).
