HELP welsh translation?

im getting a tattoo soon of the saying "every flock has it's black sheep" and i REALLY need to know if this is the correct welsh translation.
Y mae dafad ddu ym mhob praidd
thats what i have please please anyone who knows welsh help me!!!!

I'm getting a tattoo with these words in Welsh, but as always many different words come up for each word. What is the most appropriate translation for each word? Also the pronunciation for each word would be very helpful as I don't actually speak Welsh, however much I would like to. Another thing, please only answer if you do speak Welsh, I want the most accurate translation possible due to the nature of it's use. Thank you :)
The words a translator is giving me are - angerdd, annwyd, ddioddefaint, hangerdd, hannwyd, nioddefaint

I am debating getting a tattoo of this seeing as it's my heritage, and im not too strong in my pronunciation of welsh. So any help would be appreciated

I am getting a tattoo for a deceased family member,
I have a picture, and I want to get "A beautiful Live" in welsh...
I keep looking for translation sites, but nothing is helping, and most of the time they don't give you the correct use or form of ANY words.
If someone cant translate this, it'd be great.
Thank you.
I meant "A beautiful life"
Sorry :-)
Also if you could translate "My Angel"
I think angel is angylion
