Have you seen the new website, at least new to me, from the BYU Family History Technology Lab, Relative Finder?
Using the sites technology and the database at FamilySearch.org, it shows you your relationships to the world. Obviously an LDS site, it shows predefined groups such as Book of Mormon Witnesses, Current Apostles, Early LDS, Declaration (of Independence) Signers, etc. You can even create your own groups.
Interesting concept, now only if the FamilySearch database were accurate. Another reason, of many, to get the data cleaned up.
Check it out at Relative Finder, a FamilySearch account is required. .
