Problem using lists

[Sweet Lily]

Hi everyone. I have a little bit of a problem. My assignment is to create an arbitrary genealogic tree using lists in C. The entry data is from a text file under the form :

[Matilda,(John Alice)]
[John,(George Jay Ray)]
[Jay,(Frank)]
......................... "and so on"

Any tips in how to create such tree?
Thank you very much ^_^
