I have just now seen an article in the Encyclopedia Judaica about R' Akiva HaKohen of Ofen (i.e. Buda: the grandson of R' Akiva the Elder). This article suggests that R' Akiva of Ofen's father was Menahem, rather than Yitzach as shown on this GENI tree. Has anybody investigated this? Who was Menahem HaKohen? Does this raise a question regarding the pedigree shown currently on GENI? Here is the article and the sources are listed there: https://go-gale-com.i.ezproxy.nypl.org/ps/retrieve.do?tabID=T003&am... If this URL doesn't work, you can find the article on page 563 of Volume1 of the 2nd Edition of the Encyclopedia. These are the sources listed there: S. Kohn, A zsidók története Magyarországon (1884), 227–8; S. Bűchler, A zsidók története Budapesten (1901), 57–58; idem, in: Magyar-Zsidó Szemle, 27 (1910), 82–83; B. Mandl, in: Mult és Jövő, 25 (1935), 316; MHJ, 2 (1937), 537–8; A. Schreiber, Hebraeische Kodexueberreste in ungarlaendischen Einbandstafeln (1969), 122.
