ROB – yes indeed. Rav Pinchas and his brother R’ Shmuel Shmelke were also a bit unusual in that they were both Rabonim and poskim in established communities, but were also among the earliest followers (and leaders) of chasidus. It caused them a lot of controversy and problems with their communities. It also may be part of why my minhagim are a bit all over the map. R’Pinchas’s grandson married the daughter of the Mateh Efrayim, and I am descended from them, so I have the Margoliyus minhagim as well (e.g. no full kriah at Alenu in R’H musaf). Also, as you may know, R’Pinchas was an einekle of the first R Pinchas Horowitz, who married a descendant of the Luria/Spira/Treves branch of Rashis family through Yocheved) so I have minhag Rashi on things like kiddush in the sukkah but no eating on Shmini Atzeres during the day.
I actually made a point of giving my 3 younger children (my eldest has all biblical names after ancestors) both a modern Hebrew name and a biblical one.
