Need help translating for my novel

[Genevieve]

I have a few phrases in a novel I'm writing, and I need to find out the right way to say them (or something similar) in Gaelic. Can anyone help me with any or all of these? Many thanks!!

1) How are you?

2) I'm well, thank you

3) Goodbye, mother. Go with God. I love you. (she died)

4) We wish you well on your journey to eternal reward. (they died)

5) Come in!

6) What are your names, children?

7) Rest and be wi' God now

8) Good night cherished one (to a child)

9) my friend (woman to woman)

10) Are you well, my love? (man to woman)

11) Goodbye, my sweet son (son died)

[Tobus]

Well, I can at least answer this one:

1) How are you?

Ciamar a tha thu? (formal)
Ciamar a tha sibh? (informal)

[Genevieve]

Thank you! It's a start!

You should probably specify, Scots or Irish

[Arlen]

Scots or Irish and are they addressing an equal or an elder/higher ranking person.

Also, what part of Scotland are they from?
