It's a very lovely name that I think is deserving of a comeback. I don't think I would use it because there was a very crotchety old Aunt
Ruth in my family that hated my dad. :/ The name is very nice, though, and it does have a graceful and understated feel to it.
Ruth Adeline -- Nice, but I think I prefer
Adeline RuthRuth Ellen -- Meh. I've never really liked
Ellen.
Ruth Eliza -- This is lovely! Either
Ruth Eliza or
Eliza Ruth would be very sweet.
Ruth Emily* -- I love this.
Emily is a great name... in the MN spot.
Ruth Emmaline -- I'd use
Emmeline over
Emmaline, but this is graceful and sweet.
Ruth Keturah -- Not sure I like the flow on this one, for some reason.
Ruth Susannah -- Ditto. I think it's the double "oo" sound that bothers me.
