Highs and lows
The most boys given the name in a single year was 48,647, in 1952. That is not its peak year: Social Security’s records hold more boys for 1952 than for 1951, so the name’s share of births was smaller. Its best rank in any year was #8, first reached in 1880.

How these numbers are counted
Social Security publishes, for every year since 1880, how many babies of each sex were given each name, counting any name given to at least 5. A name’s rank is its place that year among names for the same sex, by number of babies. Names with the same count share a rank here, while Social Security’s own lists break ties alphabetically, so a rank can differ from theirs by a place or two. A name’s share is the number of babies given it divided by all babies of that sex in the data that year, and its peak is the year that share was highest. Shares rather than counts set the peak, because far more babies were born in some years than others: counting babies alone would pull nearly every name’s peak toward the 1946–1964 baby boom.
Source: the U.S. Social Security Administration’s national baby name data, from Social Security card applications for babies born in the U.S. A name is left out of a year when fewer than 5 babies of one sex got it, and counts before about 1937 are incomplete, because many people born then never applied for a card.
