Who are Helen and Marisa?

I am watching episode 2, and there's a flashback to the fire that led the Foy family to ultimately become the Brogan's.

Eddie bursts into the house, and shouts "Marisa!" and then notices Sean.
Outside, someone (I can't tell if it's his wife or his daughter) shouts: "Helen!"

I know that his daughter was Nikki before she was Zoe. I don't recall Evelyn's original name. So, which one is she? If either? If she's one of those names...then who is the other?

Very confusing, this show. Very good, but confusing. Love Morrissey.

UPDATE: I just rewatched the clip (it's subtitled in Chinese or something similar,) and I think the woman shouting is actually the wife, and she's actually yelling "Eddie! Eddie!" and it was lost in translation. It sounds very close to Helen, especially with that thick accent she's yelling in. The subtitles say "Helen" but I'm assuming they're wrong. So who is Marisa then? The wife's original name?

Bam, said the lady.
