Well this touches close to home.

My mother's family come from North Wales: many of the poorly mapped 
places in the area either have family associations, relatives still 
living there or other memories from family holidays or my early 
childhood. You can look at places I've mapped in the area: some are from 
short more or less annual visits to the area, others reflect deeper 
meaning: the cemetery where my uncle and great-grandmother are buried, 
the village where my cousins' used to run the post office, the house 
where my mother holidayed before WWII, the open land which caught fire 
and my father helped beat out the flames.

Llyn does have a basic road network (pace Richard).  On top of that the 
OS data is a poor substitute for exploring the rich topography of Llyn, 
or for engaging people who already know it.

So why don't we try and find some local organisations which might have 
an interest: the local councils may well log GPS traces for their 
vehicles. There is a centre at Plas Tan-y-Bwlch 
<http://www.eryri-npa.gov.uk/study-centre> run by the Snowdonia National 
Park which runs conferences & courses. There is a university at Bangor 
with a CS department. There is an incipient Welsh Placename Society 
<http://www.bbc.co.uk/news/uk-wales-11800957>. There is the Royal 
Commission <http://www.rcahmw.gov.uk/> on Ancient Monuments for Wales 
which is in beta with the People's Collection Wales 
<http://www.peoplescollectionwales.co.uk/>. In most parts of England 
there are active Welsh Societies (e.g,[1],[2]), perhaps their members 
would love a talk about OSM and the chance to reminisce about the 
villages and towns where they grew up. There are local history societies 
like that for the Nantlle <http://www.nantlle.com/home.htm>valley. There 
is the Urdd <http://www.urdd.org/index.php?lng=en>.

In other words there are lots of people & organisations with which we at 
OSM could engage, or we could just import the OS data.
