However, typing her name into google doesn't seem to be helping AT ALL! I suspect it's not helping, because I'm typing her name in Romaji, instead of in Kanji. If I had the Kanji characters, I can try sites like facebook or myspace, and hopefully have more luck.
The name I'm looking for is Tanzawa Makiko
I realise that there may be any number of ways to write this in kanji, and I am willing to google them all. The 'ko' is the kanji for 'girl', I remember that much. I think the 'zawa' ('sawa') part of her family name had something to do with the kanji that looks like a quartered square, but don't hold me to that.
If anyone can help by giving me possible kanji spellings, I really would appreciate it.

ETA: Also, say in the last 7 years or so, is it common for a Japanese woman to take her husband's surname? (if it was ever common - I'm not up on cultural conventions)
