Usually the Party (Related Party gets modelled first) and the associated entities like Lead are attached to the Related party of the Customer.
A related party to a customer can have multiple leads against the same customer. So, it is always good to model the related party first.
However, you can choose to do it the other way round, as long as the relationship is maintained.
