What origins do i have?

Question:

What origins do i have?

Can you tell ethnic percentages by your grandparents last name? My grandparents last names are:

Finley-celtic, scotish
May-English?
Long-English?
Bentz-German

Would this make me 50% english, 25% german, and 25% celtic/scottish?

Also i heard that your ethnicity is mainly determined by your fathers DNA. So if my dad has the celtic last name of Finley does that make me predominantly Celtic?

You did the percents correct. Your ethnicity is all of those backgrounds. DNA has a paternal test, where we as humans are only knowledgeable enough to determine the Surname lineage. There are Maternal tests too. You are predominanatly English if the grandparents contributions are correct.

I put some DNA web sites for you to read more.
