It depended on the time and place. Fitzroy is particularly associated with illegitimate children of the king, but until the 17th century revival of the Fitz prefix, it was mostly just meaning "son of" without any particular inclination towards or against legitimacy. But in the Stuart era it was frequently used for illegitimate children of royalty and nobility.

I think if you're the son of a gibbon, it doesn't much matter whether you're a bastard or not.

Gibbon was actually a pet name form of "Gilbert".

Being that I know of no countries which will allow you to wed a Gibbon in holy matrimony, I doubt the son of a gibbon could be anything but a bastard.
