I think this action is not available in the sims 2 because each neighbor has its own としょうかん, ライブラリ unlike the sims 3 where the としょうかん, ライブラリ is shared.
あなた need to 移動する your family with their house. click save house bin (or something like that) so that house can save with your family in a house bin collection. then go to strangetown または where ever u want and u find that house with your family bin in a house bin collection... Hope I helped ; )
