Meaning & origin

Siomara is a modern feminine name that first appeared on the U.S. baby name charts in 1969. Its exact origin is unclear; it may be a blend of the Irish name Siobhan with the popular suffix -mara, or a completely invented coinage. The name reached its peak popularity in 2006, but has since followed a falling trajectory since around 2005. Despite its relatively recent debut, Siomara has not entered the top 1000 ranked names, and data for 2025 indicates its usage remains infrequent. The name has no strong ties to any specific region or state in the U.S., as indicated by empty top-states data. Parents drawn to melodic, multi-syllable names with a modern feel may find Siomara appealing, though its meaning remains uncertain.

Siomara first appeared on the U.S. baby name charts in 1969. It is likely a modern coinage, perhaps blending the Irish name Siobhan (meaning 'God is gracious') with the suffix -mara (as in Tamara or Mara). The name gained modest usage in the late 20th and early 21st centuries, peaking in 2006, but its exact derivation remains uncertain.
