Gertrude (also spelled Gertrud) is a feminine given name which is derived from Germanic roots that meant "spear" and "strength".
"Trudy", originally a diminutive of "Gertrude," has developed into a name in its own right.
In German-speaking countries, Gertraud (pronounced Ger-trowt) is a familiar variation of the name.
"Gartred" is a rare variation (attested in Daphne du Maurier's novel The King's General, set in 17th-century Cornwall, England).
[1][2] "Gertruda" is a rare variation used in the Soviet Union as an abbreviation of Geroy truda (the Hero of Labour).
