Using the last name in search is enough to bring up all records for the surname. If you don't see the right pedigree, your results aren't in the database yet. It can take a year or more -- lately SMGF has been concentrating on mtDNA, so Y results are trickling in more slowly.

If you create an account at SMGF and ask to be put on the mailing list, you'll be notified when a new version of the database goes online.
