There is a word in English "branch":

*

*

from the late Latin branca, meaning footprint, claw, paw... which is of unknown origin, said to be probably from Gaulish...

*

Acc. to Wiki:

no certain etymology. 

*

*

My turn:

Look at the Turkish word "parmak" meaning thumb, finger and its older forms:

There are some variants like barnak, barmak that could be the origin of the all those Latin, English, PI words above. 

*

Possible?
