Isn't that map missing all those French Canadians?
Yeah, but most of them don't actually speak French, only Québécois.

Silly sounding dialect.
FWIW Spanish was my first/home language, though English is now my dominant one. I learned French fluently while living in Switzerland and took classes in German and Mandarin Chinese over the years.
IMHO German ultimately bears very little real resemblance to English, since the Normans brogught so much French into the mix. Switzerdeutsch or Dutch have many more similarities to English. Strangely, I tend to confuse German in my mind with Chinese of all things, perhaps because they share some sounds or more likely they are both weak languages I use less often than the others.
By contrast the Romance languages (at least Spanish, French, Italian, Portuguese) are all pretty similar. For example: it's fairly straightforward for me to communicate in Italy or generally understand the gist of what a Portuguese speaker is saying. My mom actually went around Switzerland and France speaking Spanish with a French accent for year or two before she took a refresher class, and many of the maintenance folks I befriended in school that came from all over Southern Europe ended up speaking a weird amalgam of the different languages amongst each other after being employed together for a few years.
All in all, learning a second Romance language can IMHO be more useful than learning German as it allows you to expand more easily to the others....
