I got my Applegate family's Y-DNA tested but find there aren't many other Applegate results to compare to. Where is everybody? If enough people participate from different family groups, we may be able to get a pretty clear picture of the branching of the family, confirming (or in some cases correcting) the Voress data ("The Applegate Family in America"), as well as providing a probable path for some people who don't know how they fit into the Voress data yet.
Now is a very good time to get tested with the great discount prices on testing happening in September (at FamilyTreeDNA.com - if you order as a new customer through a project like Apple** Surname, or British Isles 2) (or at ancestry.com - if you are a member).It looks like a 37 or 46 marker test (depending on the testing company) is what is needed to distinguish between the different lines descending from Thomas of Gravesend, Long Island.

Three of us who tested have posted our results at the free public database Y-Search . (Search By Last Name: Applegate). The fewer mismatching marker numbers we have, the more closely related we are.
