He wants to wear a kilt (he's seen mine) and I will make him one.
You might suggest that he go to www.familytreedna.com and take a look at their FAQ if he is interested in his biological ancestry. They have projects for adoptees. Testing his Y chromosome DNA is quite likely to reveal his biological father's surname, and even more likely to reveal his father's ethnicity. He could also test his mitochondrial DNA and probably discover his biological mother's ethnicity, though it would be less likely to find her surname.

It costs a couple of hundred dollars, is simple and painless, and takes about 6 weeks to get the results.
