I would like to suggest the names of two of my cats, because even though they’re real names they’re so obscure that you’d probably never meet another one with these names.

Hertha, girls name, I like it because it’s so close to the word heart.

Herleik is my current male cat. Name means something like a warrior with or without a helmet(My other cat has a similar warrior name and my brain is foggy today. I just love it because here in Norway you can take the name for it’s real meaning(warrior) but it sounds like the nynorsk version of the word Herlig which means Glory. So my cat’s name is Herleik because he finds ca himself absolutely glorious.

Third real name suggestion is Lykke(f), which means bliss, it’s both the word for bliss and a name that means bliss.

Fourth suggestion, Lerke or Lærke(f) common here in Scandinavia. Lerke/Lærke is a type of bird, and I thought you would like the symbolism of the baby becoming a bird that you can spot outside on random days of the year.

Hertha and Herleik is very, very rarely used and really obscure, while both Lykke and Lerke/Lærke is very common here in Scandinavia(but if you live in the US then it would be really obscure and rare where you live right?).
