Sindarin translation for an orphanage?

Background: An elf maid active in the great northern wars between Arthedain and Angmar founded a hidden refuge to serve as an orphanage for the children of Arthedain who have no family or neighbours to take care of them. She wants the name to emphasise that they are each other's family now. She happens to be a skilled bard.

I'm looking at Bardh-en-Nothlir, meaning Home of the Family.

Comments or suggestions?

It’s a bit of a complicated matter. I would recommend simply using en (+mixed mutation) for singular and en (+nasal mutation) for plural, based on the plural examples of Haudh-en-Ndengin, i mbair en Ndengin, and Bar-en-Nibin-noeg.
