Need help with story, names of characters, and title!

I thought of a great storyline last Sunday night for one of the characters in my story, Wanting Someone which a story I put here named Sean Connors who suffered a horrible moment in his life that invovled his wife before he moved to Washington, DC and in the chapter link I put here (LOOK BELOW THIS PARAGRAPH!) which shows a flashback of this and I really want to use the flashback as the introduction but I will add madami detail to it. Please tell me what you think about it!

Also, I already got some names for about three characters (Sean, Kate, and Danny) and one in development (I really like Ryan or Matt for Sean's brother.) but I needed some help for naming the other characters. Here they are:

* Kate's younger sister who came back tahanan after her sister died and help Sean with his mourning of his wife. Looks like Kate but with longer blonde hair and is a horrible cook!

* Sean's segundo younger sister who is a lawyer and Sean's youngest sister who is still in school to study art. Both petite with brown hair but sister #1 had blue eyes and sister #2 had green eyes. Tried to be help Sean but couldn't because of their own lives and couldn't interact with him.

* Sean's parents. Like Sean's sisters, they tired to help their son but couldn't at all. Father's a smart, kind but tough man who did a lot of things for his family to get them a better life. Mother's a homemaker who is very close with her youngest son. Pretty, smart, and sweet.

* Kate's parents who are like Sean's parents but they kind of blames their daughter's unexpected death at Sean which Sean didn't like at that because it wasn't his fault and tries to tell Mr. and Mrs. Andrews (Kate's parents) that wasn't true.

Lastly, the title. Don't know what to do with this but please think of a great pamagat or two or three for me.
