Almo is of Latin origin, derived from the word 'almus', which means 'kind' or 'merciful'. It was used as a byname for someone who was charitable or compassionate. In medieval times, it was often bestowed upon those who showed mercy towards their foes during battles.
"The name Almo experienced a brief spike in popularity during the early 1920s, with five babies named Almo each year between 1921 and 1922, followed by another five in 1926. However, this did not translate into sustained long-term popularity, as there were no other recorded births of that name throughout the rest of the century."
