So I wood be S. Plit Personality?

Fields. And most of my recent ancestors were farmers. I guess dirt is in my blood.

Maternal grandfather's name was Garner, a derivative of gardener.
He was a gardener.

So, if someone's name was "Uselesstwit" that would probably make them a politician, right? 

Martin
 
Martin Name Meaning            English, Scottish, Irish, French, Dutch, German, Czech, Slovak, Spanish (Martín), Italian (Venice), etc.: from a personal name (Latin Martinus, a derivative of Mars, genitive Martis, the Roman god of fertility and war, whose name may derive ultimately from a root mar ‘gleam’). This was borne by a famous 4th-century saint, Martin of Tours, and consequently became extremely popular throughout Europe in the Middle Ages. As a North American surname, this form has absorbed many cognates from other European forms.English: habitational name from any of several places so called, principally in Hampshire, Lincolnshire, and Worcestershire, named in Old English as ‘settlement by a lake’ (from mere or mær ‘pool’, ‘lake’ + tun ‘settlement’) or as ‘settlement by a boundary’ (from (ge)mære ‘boundary’ + tun ‘settlement’). The place name has been charged from Marton under the influence of the personal name Martin.
 
Roman God of fertility and war...I can live with that.

Hey Bit,

I can trace my grandmothers ancestry through the Vikings and Northern Scotland as well.

I was in my early 20's when she first pulled out a copy of the genealogy for both her and my grandfather, she said that she wanted to make sure that she gave me copies while she was still alive. When she got to one point in the lineage, her voice got real quiet and she whispered....."and this is where we changed the family name, we were desendents of the Vikings." I always thought it funny, because there was no one in the room, but the two of us.

I had always assumed Barnes was related owning or barn or working in a barn. Intrestingly there is an alternative source.

name borne by the son or servant of a barne, a term used in the early Middle Ages for a member of the upper classes, although its precise meaning is not clear (it derives from Old English beorn, Old Norse barn ‘young warrior’).

That's interesting, maybe the Scots 'bairn' (child) came from the Norse then.

Interesting topic, Sir Strummer,
 
In the Netherlands we have these 7 types too. What I noticed is that each type is more dominant in a particular region. Examples:
In the Southwest of the Netherlands; Patronymic, matronymic, or ancestral
In the South of the Netherlands:  From an Dutch place name
In the East of the Netherlands: From a geographical feature of the landscape

bapu
I was told mine is derived from cup/container. My ancestors in Poland were probably potters.
 
I just changed the first "t" to "s".

Isn't Bapu a name more common in Mumbai?

My guess: Amsterdam.
