What was Rembrandt Monkey's Name?

I'd guess nobody knows or really cares what that monkeys name is,... so we'll just call him Monkedo. It's all supposedly a myth anyway, so who really cares? That supposed stupid story of Rembrandt painting his dead Monkedo into a family portrait after he had just kicked the bucket, or his son Titus holding a monkey instead of a parrot, does sound a little bit absurd and hard to imagine for most experts.
