FD could have been Hibiscus

I know of a person whom I address as Auntie Ruby. Auntie Ruby is a mother to 3 kids - 2 daughters and a son. Their names are Emerald, Pearl and Jasper.

Well, I know of another person whom I address as Mum. Her maiden name is Rose. Can anyone make a wild guess as to what I thanked God for this morning?
