Are you trying to locate some relatives? Petersen is a very common surname here, so if you're looking for someone they might be difficult to find. Lam on the other hand I've never heard as a surname before, and Nordby on Samsø is a small village, so you might have better luck finding people there. Though I doubt any member on this website lives there, at least the odds are small. By the way, 'lam' is the Danish word for 'lamb'
