THE BACH FAMILY --- johann michael bach + johann christoph bach III

then we have these two handsome young men, Johann Michael Bach I(1648-1694) , for his part Leopold I of austria (and portugal)...he was father-in-law to JS Bach...

and next in line...

Johann Christoph Bach III (1671-1721).... he was apart from his composer identity also Emmanuel Lebrecht, prince of Anhalt-Köthen...and  if he has an identity of lower royalty, it means almost automatically he also had several of higher royalty...i just havent found them yet... dont mix him up with his contemporary, another Johann Christoph Bach (1645-1693) who was none other than edmond halley / georg friedrich haendel...
