Jacco or Francis

I think both names are quite old-fashioned!
Jacco really reminds me of an old man. Like from around 50-60 years old, and when you hear that name for a child/young adult, you immediately have an image of him in your head.
I think Francis sounds more like a girl's name and a bit too "gay-sounding."

If you don't know whether you think Jacco is a nice name, why are you still doubting it?
And what do you mean by saying there's nothing on the site that fits, because he's a big, long baby? Is he already born but you just don't know the name yet?

I think this is just his 12-year-old kid who has nothing better to do!

I don't think either of those names are really nice either!
What do you think of:

Jaco (sounds a bit newer than Jacco)
Yannick
Niels
Enzo
Vic (if used as a full name, you could also go with Victor, but as a nickname, Vic)
Samuel (also very nice)
Job
Jari
Jake
Jamiro (was on my list, but my sister named her child Jaimi, which unfortunately sounds too similar)
Jairo

Do you already have children?
If so, what are their names? You can see what goes well with them.

Good luck!
