Neta comes from he Hebrew - it is the root Nun-Tet-Ayin which has to do with planting.

It is supposedly biblical and appears in Psalms 104 verse 16 where it refers to the planted Cedars of the Lebanon. It also appears in Isaiah Chapter 5 verse 7.  The connection is a the "rooting" of a person in his heritage

Neta (planted) in Hebrew has no connection to Nathan  which is rooted in the word "given"

Google shows examples eg Natan Nota Eibeschutz, Natan Nota Kozlowsky, Natan Nota Ragoler etc.  Does Nota come from the same root as Neta?

The famine name Neta came out from the German names Ageneta or Agnes.
In the 17 century we can find it in the book "Beit Shemuel" about jewish names, 
Alexander Beider in his book" Ashkenazic Given Names" write that this name was find in 1347 in Frankfurt 
and after this time also in 1546 in Prague and in more towns in Europe.
My conclusion is , that famine name Neta was very old and where  used from the middle ages in Jewish families.

Hi Harvey, 
The answer to your question is both yes and no. 
The spelling of both names Neta and Nota (both נטע) suggests they relate to a planting or seedling. The strange thing is that in the common combination of men's names Natan Nota (נתן נטע) the name Nota is probably a colloquial/shorthand nickname for Natan and doesn't have to do with Neta or planting despite the spelling.
