Ok so I'm welsh but i only know English and i would really like to learn welsh so i can know what my grandparents are saying and would like to go there and to be able to know what im saying. thanks for all of the help!!

My mom and dad divorced when I was little and I haven't seen my dad since. I've always been interested in learning about my ancestors but I can't find anything about that side of the family because I don't talk to any of them. All I know is that they are Welsh+German(My grandparents both lived in the USA, but I don't even know if they were born here). Is there anything I can do?
