I've added 私なり. Looking at the Tanaka sentences I see 6 for this なり: 君なり, 私なり, 彼らなり(2), 自分なり and 彼なり.

自分なり　	1602767 (already an entry)
私なり　　	589649
彼なり　　	100542
僕なり　　	94219
彼女なり　	45580
俺なり　　	36871
あなたなり	35322
君なり　　	11165
あの人なり	941

I can see the use of this and the 彼なり entry for glossing. 私なり should probably be an entry too, then.
I don't think this is adv - 彼女なりに is the adverbial form, isn't it?

I have to agree. There are several usually-in-kana なりs, and unless someone is on top of the pronoun+なり pattern it can be misleading
Apropos of text glossing, WWWJDIC's current approach makes a hash of the 私なり pattern because it defaults to the particle なり. The experimental version which preprocesses using MeCab at least picks up the right one although the actual translation gets a bit lost because of the breadth of entries with 形 as a surface form.
I'm leaving this open for a bit as I want to address some other pronoun+なり patterns and there is some sentence indexing to be fixed.

I find it useful for text glossing. なり has many disparate meanings, and if you don't know beforehand that it means "way; peculiar to" when placed after a pronoun, it can be hard to piece A with B.

I don't think we need this or 彼なり. It's just 彼/彼女 + なり. We don't have 君なり or 私なり.
