Heidi, Erin or ?

[NovemberRainbow]

Interested in opinions on Heidi or Erin, to go with Siblings Grace and Eli.

Other suggestions welcome.
Middle name will be Susan after a grandparent.

Hope Grace Eli

Grace, Eli and ..
Heidi Susan
Susanna Erin

I much prefer Erin, personally, but agree it's not great with Eli already.

Never been keen on Heidi, I agree with the 'twee' definition - hi-dee-hi!

Alternative suggestions with Grace and Eli:-

Alice Susan
Lara Susan
Mia Susan
Freya Susan
Olivia Susan
Lydia Susan
Harriet Susan
Zoe Susan
Verity Susan
Clara Susan
Matilda Susan
