Is Marily a boy’s or a girl’s name?
Marily has been recorded only for girls: SSA lists no boys with the name in 71 years of records (it lists a name only in years with 5 or more babies of a sex).
Girls and boys named Marily: the SSA national file counts each sex separately.
How many people are named Marily, and how old are they?
An estimated 809 Americans named Marily and born in the U.S. are alive in 2026 (93% of everyone recorded); the median is 27 years old and half are between 18 and 42. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 1,236 people named Marily (1,224 women and girls, 12 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 777 born in the U.S. The Census count is 1.6 times that prediction. Possible reasons: the Census records the name people give, which for many is the short form Marily rather than the name on their birth record, and it counts people born abroad, whom SSA’s files leave out.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made. Count: Census Bureau, first names in the 2020 Census (released April 14, 2026; names reported 100 or more times, with the Bureau’s disclosure-avoidance adjustment).

Where Marily is more common than its national share predicts
Relative to its national share, Marily is most over-represented in California: since 1930 it was given 1.2 times as often there as its national share each year would predict.
States: SSA state file, 1910-2025, published May 8, 2026; births count girls and boys together, and the rank is among girls’ names in the state in 2025. The file leaves out any state and year with fewer than 5 babies of the name, so small states are undercounted; each ratio compares the state’s births of Marily with the births its national share predicts year by year, for states with at least 100 births of the name.
How common is the spelling Marily?
Marily is a less common spelling of Marilee: SSA has recorded 875 Marily and 7,434 Marilee since 1880.
Of these 8 names spelled alike, given to 114,254 babies since 1880, Marily is the eighth most given (<1% of them). In 2025 it was given to 9 of their 1,620 babies (<1%), the seventh most given that year.
Spelled alike: names in the SSA national file with the same pattern of letters and sounds and at most two letters apart, and Wiktionary’s listed forms; births since 1880 and in 2025, and each name’s peak year, from the SSA national file, published May 8, 2026. Some are separate names, not spellings of one.
