Liah is a spelling of Leah and Lia, the Hebrew name of Jacob's first wife in the Book of Genesis, which is usually explained as "weary" and sometimes as "wild cow". The added h makes the short name look a little fuller, in the style of Mariah and Aliyah. Liah stood at number 5604 in 2000, reached number 1273 in 2018 and ranks number 1322 in 2025.
