Yes!
My real name is Eoin (pronounced Owen basically; very-very-old Irish for "John").
There is a hiker in HGSS' Kanto on the route between Cerulean and Rock Tunnel, and with HGSS being my favourite game I was ECSTATIC to encounter him.
I was further surprised in XY, I cannot for the life of me remember the town names but there are a Brains and Brawn duo called "Eoin and Wolf".
So, neither of my game-name-sakes are exactly impressive trainers, but it's still so cool to see "my" name in the games. Haven't come across any other Eoin's so far, I tend to leap from my chair when it happens haha.
