Anciennes figurines rituelles africaines sculptées, ancêtres masculins et féminins, Congo ? Nkishi ventes exceptionnelles ?

Hand carved African figurines purchased at a thrift store on the southern border of Texas at Mexico.  I have little information on these, other than that they seem to belong together and should be with in a place of honor. 

From what I can tell, they may be from the Congo, and may have belonged to someone who traveled to African for work, study or pleasure.  The photo of the Maasai was with the two figurines, along with a carved crocodile that was badly broken.

I believe they are from the 1970-1980s; maybe older. These do show some wear. The red V or check marks were made by the thrift store. Height of both approx. 9 in. Base of each aporox. 2.5 in.

Information welcome.
