Rheva, derived from the Welsh 'Rhiannon', means 'great queen'. It is of Welsh origin and has gained popularity in recent years as parents seek unique yet meaningful names for their daughters.
"The name Rheva saw a spike in popularity between 1918 and 1927, with peaks of seven births each year during those periods. However, its usage then declined, with five births each in 1936 and 1944. Overall, there were 35 babies named Rheva over this period."
