Those are lovely simple names. Just go with your instinct.
Dd had 2 middle names, one my mothers name which I always wanted as a middle name and is a lovely classic name. Then we felt bad for DH's mother so stuck her name in as well. Her name is abit unusual.
TBH I regret it now. Really dont think DH's mother would have given two hoots about only my mums name being used. Now dd has a really long unwieldy name and I have found myself dropping the second middle name when doing forms etc. However dh uses it religiously so it all gets abit confusing. So if you want 2 middle names go for it but be sure you can really be bothered if in doubt leave it out!
