Babies given each name, 1880–2025
Sydelle Sydnor
Each line is every baby given the name that year, girls and boys added together — the only count that means the same thing for both names. A line breaks where the name fell below five babies in a year — the point at which the SSA stops publishing it — rather than being drawn through a figure nobody published. A single published year in a gap shows as a dot.
Who was ahead
Sydelle has been the commoner name in every year either was published, 1906 to 2025. The lead has never changed hands.
The closest they came was 1925, when Sydelle had 24 and Sydnor had 7.

A rank is a position within one sex’s list for one year, so the two rank rows are not subtracted from one another and the winning column is not marked on them. The living figure is a life-table estimate, not a count.
Which name is older
Half of the Sydnors alive today are over 100; half the Sydelles are over 75. That is 25 years between them: two names in use at the same time, worn by two different generations.
