Are Joanna and Joseph too similar?

[Aceson]

1 as 1 DC's middle name and 1 as 1 DC's first name.

Thanks!!!

It's fine as a first name and middle name but I wouldn't use them as both first names as only one of them could use the nickname Jo/Joe

I'd say yes if they were both first names as they'll both inevitably be shortened to Jo/Joe. But I think that's fine if one is a middle name. Other than a birth announcement nobody really uses a middle name daily anyway.

Fine if one's only a middle name

I think it's fine

I knew a Joanne who had a baby Joseph. Actually it never occurred to me that they were similar at all!

Absolutely fine !
Joanna-Jo
Joseph-Joss

Fine if one is going to be a middle name
