There are currently no dedicated stickers for either of these. The Russian Roots Project lists the Nonmigrating Ancestor template as the preferred template to use. Lithuanian Roots is still a Free-space Project, so I would suggest using the same template for either instance right now, as an example:
|flag = European_Flags-32.png
|tooltip = Flag of Russia
|addinfo = <Name> was born in Russia.
|flag = Flags-13.png
|tooltip = Flag of Lithuania
|addinfo = <Name> was born in Lithuania.
The addinfo= parameters can technically be any text you like that fits the theme of the template (having to with a location).
If you would like a new Sticker, you can propose it in G2G using the STICKERS tag. Include your thoughts on what it would say and give examples of profiles you manage that you would place it on. If three or more other active members say that they would also use it on profiles they manage, and there aren't strong objections from the community, it can be created.
