Royal Blood is a database that says (in March 2011) that it "is home to the world's largest single published family tree that's freely available online". It invites people to submit a GEDCOM for incorporation then "watch this page for news of the next version coming later in 2010". It also says "To comply with privacy regulations worldwide we have removed anyone from the tree who is likely to be living."

((The publishers of Geni.com might question the first claim.)

The index key does not strictly search for surnames. For example, the first nine pages listed in a search under "F" on 27 March 2011 were: ? F.A.Burguin Matthew Dawes F.G.S. William Horton Lloyd F.L.S. R. Nasmyth Esq. F.R.C.S.E. ? F.R.Marbot Erasmus Darwin M.D. F.R.S. Samuel Galton F.R.S. George Allan F.S.A. Jacob F.Walker

There is no finer division of letters, so if your target name starts with "Fo", for example, you need to use your scroll block to work quickly through tens of thousands of entries.

When you reach an individual's page, you see the name "Royal Ancestry File" and the greeting "Welcome to the largest genealogical tree on the internet with over 1.4 million indivduals.[sic] below The figures in square brackets show the number of relationships required to connect to Charlemagne."

The page has several panels below the heading:
 * 1) Google ads
 * 2) Basic data: name, birth, christening, marriage, death, burial, sex
 * 3) Ancestry tree
 * 4) Children (with an indication of how many children each child had)
 * 5) Comments (which may be submitted by anyone)
