Family trees

Reading petes blog today about the 1911 census being released got me to thinking about my family roots, we have done quite an extensive search on my maternal and paternal sides of the family. anyway in happens to be that my nans side originated in Callington cornwall and also from essex
Now i have lived most of my life in essex and now cornwall without knowing any connections to these places so my theory is :-
1: are our lives mapped out for us even though we don't know it, is it an inbiult sub-conscious we have that draws us to these places?
2: We have already lived before and are acting out the same life in different times?
3: Or is it just fate?

I can hear you PETE chattering and laughing "load of old rubbish" but who knows for sure nobody?!!
Oh yes and we do have a ghost who resides with us here is it one of my long departed ancestors must be said she seems quite friendly!
