Hans or Johann name and Engel family to Australia

I notice in my research the name Hans and am wondering if Hans in Mecklenburg
is short for Johann? or is it short for something else, or is it just Hans or Hanns?

According to the faq page at Dieter Garlings website there is a list of first names in
Mecklenburg with the common abbreviations. Hans is not one of them. See the FAQ at:

I had a family from Southern Australia email me on an Engel family that immigrated to

Also there are more in the Lyndoch area of South Australia,

According to her note:

In the Barossa Valley in South Australia I noticed the names related to you. Several Germans settled here
after leaving Germany to follow Pastor Kavel due to religious persecution and there are quite a number of
people here with the same surnames that you have listed e.g. Schroeder, Lehmann, Lange, Bruhn, Hinze -
the Barossa has a high number of Lutheran Germans. As I said the area has several Germans, I can
remember as a child people only speaking German to one another in the stores.

If anyone has any families from Australia that are linked back to the old duchy of Mecklenburg-Schwerin
from Neukirchen near Buetzow, particularly the Engels please let me know.
