Dad-- I definitely like Chris better, it sounds more modern than Charles.
Mom-- Hope, it is a beautiful name and sounds nice with Chris, i think Emily is a younger sounding name and Christina would clash with Chris.
Brother-- Brandon is my favourite out of the three you have chosen, but I prefer Brendon. Brendon/Brandon goes well with Tara. Adam is very common so I suggest you try something a little different, and I just don't like Hunter as a name.
And, I love the name Jace, it is a really strong name that you don't hear very often, good choice. And I like Bridgette as well, it sounds nice with Brendon/Brandon and is just a very pretty name in general.
For the main family I suggest Summers, it is a nice name that fits with most first names. Plus it sounds really good with Tara, Tara Summers.
How about something that starts with a T for Jace. Like Taylor, Jace Taylor, that sounds good. Actually, i quite like it.
And for Bridgette I think a "Sh" sound at the beginning would sound good. Something like Bridgette Shaw.
Hope this helped!
BEST OF LUCK!!!
