Derry linesman strikes again

I see the linesman at the centre of the Shels-Drogs controversy was Ciarán Delaney (or at least, it was he who Fenlon pushed, so I can only assume it was he who flagged the erroneous offside which started the controversy).

The linesman for our game in Derry who did the same thing, apparently, was Clive Delaney's cousin. Which means someone with the surname Delaney is a fairly good bet to have been the same person! Two shocking offside decisions in two games!!

How did Clive's cousin get to ref a match he was in? Is it too much to ask that no relatives of a player officiate their own match?
