Anyone Irish around to answer this Irish names question?

In a story I am writing, a main character is from Belfast. I need to inquire about certain aspects to make sure I didn't make an unrealistic choice of names

1- I s the family name O??Hara common, or at least could be found in Belfast? If not could you suggest more "Belfastian" family names?

2- Which of the following female names is impossible for an Irish girl?
-Fairy
-Megan
-Bridgette
-Victoria
Do you suggest better names? keeping in mind the character comes from a very religious family.

3- Do you suggest certain traditions or traits or character flavors or biases or tastes or dialect aspects .etc..which i could give to my character to make her sound more like a Belfastian girl?

Thank you.

My Great Grandmother came from Ireland, (my paternal grandmothers mother) and is said to have come from the country side near Belfast. Their last name was Kane, and her first name was Marion. Her mothers maiden name was Mary Anne Brown.
