[ANSTHRLD] German surname sources

[Mike Wyvill]

I am trying to find the family name 'OTTE' for a client. I am at a real 
loss. While I find mentions of the name online, those are found on those 
site interested in selling you something they claim is your family arms.

I have found 'van Otte' but of course that's Dutch. I have found some 
mention of the name being Bavarian in other sources but cannot find it 
specifically other than a mention that it is a spelling variant of OTTLE as 
is OTT, OTTEN, OTTEL, etc.

Can anyone help me?
