Only consonants count here. Cheasley in 1916 called this sum Impression and credited Julia Seton with discovering what consonants reveal, and Wilson in 1922 used the same word. Taylor in 1926 tied consonants to the physical body and the impression a person makes on others.

Coffman in 1927 is the one old writer with the phrase Personality Number, and by it he means all the letters in a name as usually signed, so his sum is a different one. Today's narrower meaning keeps Cheasley's and Taylor's method under the words Coffman used for a different sum.

Elena Rossi gives 1 this way: L and N make 8, R, S and S make 11, and 8 plus 11 makes 19, which takes two steps down to 1. Taylor gives the consonants J and S initiative and daring, and modern books read a Personality of 1 as an impression of self-reliance. Walton's 1914 word for the number, self-centered, gives the less flattering version.
