Mabel

While Mabel is certainly not a standard Polish name, it has had some use in Poland nevertheless. As of January this year, there have been 21 women with this name in Poland. I wouldn't be very surprised if people often mispronounced it here as MAH-bel.

Also used in Spanish. There are 1.055 bearers of this name in Spain and was most common in the 1970s (source: Instituto Nacional de Estadística).

In 2018, 86 is the most common age for an American (U.S.) Mabel who is registered female with the Social Security Administration. It is the 1, 088th most common female first name for living U.S. citizens.

Also a rare boy's name in the United States in the first decade of the 20th century, but now completely obsolete in that role.
