In the books
In the A Song of Ice and Fire novels, the Lannisters of Lannisport have the same blond hair as the main branch, however theirs is straight, unlike the curly hair of the main family. The only Lannisters of Lannisport mentioned in the books are Rosamund, a handmaiden to Princess Myrcella Baratheon, and Maester Theomore, a maester in service at White Harbor.
