How to reach the uncle using jquery

Answer 1

You could use $.parent and $.prev assuming your uncle is always above your father:

$(this).parent().prev(); // where 'this' is #me

You could also go all the way up to your grandfather, and find uncles from there:

$(this).parents("#grandfather").find(".uncles");

Or you could search your father's siblings:

$(this).parent().siblings("#uncle");

I would encourage you to read the Traversing portion of the jQuery API for various other methods.
