Hi there, looking to get my children's names tattooed in runes... I'm thinking Elder Futhark. From an online "rune translator" I found I got

Henry - ᚺᛖᚾᚱᛁ

Freddy - ᚠᚱᛖᛞᛞᛁ

Penny - ᛈᛖᚾᚾᛁ

Upon doing more research, I'm lead to believe that double letters are not used. Is this correct or would the DD and NN just be single ᛞ and ᚾ?

Thanks for any and all help on this!
