Etymology of 'ends' or 'the ends' and other current British/London slang

I'd like to know more about how 'ends' came to mean 'hometown' in current London slang. I have heard it used to mean money, which is an extension of mainstream use - means to an end, for one's own ends etc. Can anyone enlighten me?

Also, is there are decent source of general etymological information on current slang words? I know a lot come from Caribbean words and American hip-hop but a central source would be great.

The London slang ends probably came from Jamaican slang, where it seems to have been more generic or local.

The London Slang Dictionary Project ("written by teenagers for their peers and for their teachers") includes:

Ends - Area, neighbourhood

From ends — one who is “from the streets” and so knows what’s going on.

The second highest definition in Urban Dictionary is the London one:

your 'ends' is your area

"what ends you from?"

A similar meaning can be found in this Jamaican Slang Glossary:

Ends- A place. Mi a go pon one ends still.
(I am going to one place).

And in Backayard Magazine's patois guide:

ends, colloq. home, familiar place.

Another Urban Dictionary definition includes both London and Jamaican meanings:

Jamaican word for street corner
London word for dodgy area

Mi pon di ends (Quote from Dwayne of the Verne)

Rah, SE22? You on the ends bruv (quote from Andrew of SE5)

West Norwood? Wha yah wanna move there to, thats verging on the ends man (quoute from Philly of SW16)

The W?Dictionary of Jamaican Dialect i.e. Patois says:

Ends: (n.) Hang out spot/area, place to chill,
(v.) ends out: the act of hanging out

Finally, Talk Jamaican says:

ends : destination, home (pon de ends = at home)

Some of these Jamaican definitions say ends is a destination, so the place at the end of a journey.
