Leos (or is that Leoes?)

(Maybe Dr. Sills can tell me what the plural of Leo is supposed to be?)

Tonight Leo met the third Leo he's known in his short life. The first was another baby at one of the daycares we looked at (not the one in which he's enrolled), the second was a 40-something year old man we met at the party for Rick and Marnie, and this third Leo was a 30-something year old man at our neighborhood association meeting. For a name that is not all that common any more, I find it amusing that there are four Leos who are in three different age brackets who have met in the last two months.
