You can make your own custom stickers, this is what I've done for my Bulgarian profiles.
{{.Nonmigrating Ancestor
| flag = European_Flags-40.png
| tooltip = Flag of Bulgaria
| addinfo = Dobry Mitev Vanchev lived in Bulgaria.
}}
For Cuba instead of European_Flags-40.png it would be Flags_of_North_America-5.png and then you would put your ancestor's name right after the addinfo = and then of course "lived in Cuba" instead of lived in Bulgaria. I placed a period before nonmigrating so the template would show up, so take that out. If what I wrote isn't clear (I don't think I'm describing it well) you can see here:

This is the main page for the stickers, there's a couple of general use stickers on that page but not many.
