I don't think I really understand what you want. In the general case
tables may have many parents, and it all can get quite messy.
This query first lists all tables that does not have a foreign key,
and then those that have.
select o.name
from sysobjects o
where o.xtype = 'U'
order by case when exists (Select *
from sysforeignkeys f
where o.id = f.fkeyid)
then 1
else 0
end, o.name
