The best chess couples?

This afternoon, a non-chess friend asked me if chess players date or marry each other? The obvious answer is yes but it wasn't something I thought about until I was asked this question. Which are some of the most formidable chess couples in history? (ex or current, married or committed dating)

Some pairs that come to my mind are:

GM Ivanchuk - IM Galliamova (x)
GM Shirov - IM Cmilyte
GM Lautier - IM Skripchenko (x)
GM Grischuk - IM Zhukova (GM when rating = 2500)
GM Gulko - WGM Anna Akhsharumova Gulko
GM Shaobin Wu - GM Jun Xie
GM Kosashvili - IM Sofia Polgar
GM Al-Modiahki - GM Zhu Chen
