Do you mean the Ferreiras on EastEnders? They had a ridiculous storyline which involved Johnny Allen "ordering" them to leave Albert Square because of some sort of turf war involving their taxi service ... I think ... if I remember correctly.
They have been gone for ages, not a popular family so they were got rid of pretty quickly I think. The guy who played the Father's work permit ran out so he had to leave the country and that messed up the storyline they had planned.After that they didn't seem to know what to do with them.Saw one of the boys(Ronni) in that film on Channel 4 on Saturday nite - 28days later.
