To "Run with the Fox"
- PM to you not possible
- My e-mail to the address quoted in your profile repeatedly delayed/not accepted
So here are some more details:

In your post of 12/30 you tell that your name is derived from
Muranski -> Muran -> Morin.
Now:
There exist in eastern Slovakia (southeast of Lower Tatry mountains):
...
Muran (town/village)
Muransky hrad (=castle)
Muranska huta (town/village)
Muranska zdychava (village)
Muranska narodni park (national park)
....
Many names in central Europe are derived from the
towns/villages the ancestors lived in and just the Slavic or
German ending added...
My theory:
Your ancestor originated from the area of Muran ...added
the Slavic ending of "sky".
He moved from the mountaneous/rural east Slovakian
region to the industrialized Czech region for jobreasons...
My hint to you:
"Go east man, go east and locate your roots.." and
add to your hobbies guns from Nowotny,Faukner, Morgenstern,
Holecek and obviously also Lebeda ...
Kind regards
