If I have more than four children someday, the fifth one–if it’s a girl–might just be named Ethelreda [name_u]Haven[/name_u]. Thoughts? And don’t worry about if I’ll actually use it or not, because (look at my signature!) I’m not planning on having kids for a loooooooooooooong time! 
Ethelreda seems long and clunky to me. I much prefer the simple and sweet, [name_f]Ethel[/name_f].
I like it [name_f]One[/name_f] of my great (times a lot) grandma’s was an [name_f]Ethelinda[/name_f], I much prefer Ethelreda.
My great grandmother was named [name_f]Ethel[/name_f] [name_f]Elizabeth[/name_f]. I just recently found out that I had a great-great aunt named [name_f]Ethelyn[/name_f]. I like these options better than Ethelreda which is kind of hard to say
I like it! Ethelreda is more romantic than just [name_f]Ethyl[/name_f] is, although [name_f]Ethelyn[/name_f] is pretty awesome too.
Never heard about this one. It’s kinda mouthful for me, but I can see the appeal.
St. Ethelreda was also known as [name_f]Audrey[/name_f]. I prefer [name_f]Audrey[/name_f] [name_u]Haven[/name_u] as a combo as it’s not so jarring. Ethelreda [name_u]Haven[/name_u] looks and sounds odd because the names are such a mismatch - one ancient, clunky Anglo-[name_m]Saxon[/name_m] name with a trendy word name. Your combo has a 180’ degree difference in styles so it just doesn’t gel for me.
I think Ethelreda is too much for me. [name_m]Just[/name_m] [name_f]Ethel[/name_f] would be daring enough and much more wearable in my opinion.
I agree with @nono.
Reminds me of [name_f]Esmeralda[/name_f], which I prefer
I agree with this completely. Ethelreda is quite a mouthful.
