Uh, Joanna was Gill's daughter. Although...

Oh, you're right! I got that wrong with Joanna, his daugther is in fact called Joan. Thanks for correcting me.

hrant, right on. With Gill, anything's possible.

PMN Caecilia by Peter Matthias Noordzij, called after his wife Cécile.

Ela was designed by Gert Wiescher and named after his wife, Michaela.

You'll have to ask Sander Wolf the reason he named Sticky Annie after his wife.

Haha, great stuff. Any more?

You guys can't leave a chance of making a pun on Gill jajaja...

I always wanted to know who Lilith was named after.

Another interesting case is Mrs Eaves:

This typeface is named after Sarah Eaves, the woman who became John Baskerville’s wife. As Baskerville was setting up his printing and type business, Mrs. Eaves moved in with him as a live-in housekeeper, eventually becoming his wife after the death of her first husband, Mr. Eaves. Like the widows of Caslon, Bodoni, and the daughters of Fournier, Sarah similarly completed the printing of the unfinished volumes that John Baskerville left upon his death. (from http://www.myfonts.com/fonts/emigre/mrs-eaves/)

What the hell was that?
