The Linthicum name has many variations, and has changed since the early 1700's. It has never been proved or disproved that the origin is Welsch, but it could also be English. Prior to the early English/Welsch years, it probably was of a locative origin. Many early individuals got their name from their profession (Smith, Falcon etc.) or from a location. A possible origin is from the Welsch language. In Welsch, the word "Lliant" means stream, and the Old English "Lynt" means a Flax Field. Also another form of Old English is "hlinc", which means a reidge or hill. the last part "cum" possibly is the variations of "coombe" which means "narrow valley" This explanation is not conclusive, but a possibility.
