I've noticed a marginal note in minuscule 69 on fol. 40r at the bottom on the right hand side. It might read something like μαινα, which could be a variant of the name Μεννά (cf. μαιναν in 038, 22, 79, and 343). What do you think? There is an asterisk right next to line 31, which might be an indication to look at this note. Μεννά is one of the names that one would expect to precede Ναθάμ. Maybe this marginal note is worth mentioning in the transcription of Lk 3:31 as an addition.
