(NEXSTAR) — Ever considered changing your name? Depending on what your first name is, it’s likely you have. Data from the Social Security Administration shows certain names are changed more often than others.

The administration recently told the Washington Post which names are the most often changed. WaPo says the administration used information from 2017 until the present — and the top 2 most changed names were the atypical “Issac” and “Chole.” These are believed to be misspellings of “Isaac” and “Chloe,” respectively, though it’s noted there’s no way to know for certain.

Rankings also include the names people often change their names to.

According to Behind the Name, which tracks name etymology, genesis and popularity based on scholarly linguistic sources and a user-submitted database, “Isaac” — which originates to Hebrew and the Old Testament — has always been commonplace. Since 2001, “Isaac” has remained within the top 50 most popular names, per BtN data.

It’s also important to note that though “Issac” may be a misspelling of “Isaac” for some namers, the spelling is a variant of “Isaac” in some cultures.

“Chloe,” meanwhile, appears to have fallen out of favor around 1943 — when it was ranked as the 952nd most popular name — before seeing a resurgence in popularity around 1982, Behind the Name reports. Chloe eventually cracked the top 10 in 2008, and has stayed in the top 30 since. In 2021, Chloe was actually the 24th most popular name.

These are the names that increased in popularity between 2020 and 2021.

The Social Security Administration’s popular names database contains names given in the U.S. and District of Columbia starting after 1879. The administration explains there are certain restrictions around its data, including incorrect birth certificate information, various spellings of certain names and potential ties needing to be broken.

Per SSA, 2021’s most popular baby names are Liam, Noah and Oliver (ranked first through third) for males and Olivia, Emma and Charlotte for females.
