K, I answered my own question. However, the article did remark that the question was a "popular" one.

So, in this article, Chasten Buttigieg is listed as the husband.

My assumption was the Pete would naturally be the wife. However, based upon the previous article, it appears that they could
both be husbands. I had read awhile back about a gay couple back in the day listing themselves as husband and wife. That verbiage could have all changed since then, though. I did search for that article but didn't find it.
