The name "Tallagh" is of Irish origin, typically associated with place names. It is derived from the Irish word "talamh," meaning "land" or "ground." In some contexts, it can also refer to a "hill" or "mound." Tallagh may be used as a personal name or as part of geographic locations in Ireland.
"Sean" without an accent means "old," (with an accent mark it is the name "john") and "talamh" (pronounced talav) means "earth." "sean talamh" = "old earth."
