Alcaidesa, well most of William Hill Gibraltar live there and lots of both gibraltareans and other nationalities, my friend lives in a nice 2 storey villa with garden and sharing a pool with large grassy area at the bottom of the garden. The pools always good for getting to know your neighbours. I think she pays euro800/900 per month for it. Santa Margarita is quieter, lots of empty places so good deal but less brits definately. La Linea wouldnt really suit a family, now i see you have family. Los Barrios (furthest away but not far- look at a map), would be the most Spanish, but a friend there really loves it, it has a mix of nationalities, they also live in a complex sharing a pool.
