Does the anachronism matter? It’s actually even braver for using a modern term.
Also, I’m not sure it’s an anachronism. The concept of “wanted” children (that is, wished for by a married couple) and “unwanted” children has been around for a long time, and IIRC the eugenicists of the turn of the century mentioned it. Since, naturally, a “wanted” child would only be one born to an upper or academic class white couple...

As the article says, it is complicated.

He has gone to Germany to live in the hopes of obtaining a divorce there.
Not that Edith is without dishonor here, but it is complicated.
