Solution 2

I would set up two tables.
[persons_table]
personId (primary key), name, firstname and all the meta data you need

[relations_table]
personId1,personId2,relation

~~With this you have a 1:n relation between [persons_table] and [relations_table]~~
As Manfred stated in his comment, this is a n:m relation of person_table on itself.

What you describe is actually an n:m relation an not 1:n plus it's not a relation between persons_table and relations_table but rather a n:m relation of person_table on itself.

Well, I must admit your right :)
