Shammie is of Hebrew origin, meaning 'to hear'. It is often considered a variant spelling of the more common names Sam and Sammy. The name gained popularity in the late 20th century and early 21st century, likely due to its trendy sound and association with familiar names like Samuel. Shammie has been used for both boys and girls, although it is perhaps more commonly used as a female name today.
"Shammie was quite popular in 1974 with five babies born that year, but overall, it hasn't been a widely used name with just those five recorded."
