maddrell - according to Moore it derives from a Lancashire placename - first found as MATHERELL (tho not quite clear where the exact place is)- W W Gill however states "It is probable, however, that the Manx Maddrell is an occupation-name, see Bardsley, English Surnames, page 323, where he cites a Lawrence Maderer of York, 1415. Madder and indigo are the two parent dyes from which most others are obtained, and a madderer was a dyer in the former colour. It was an old English surname occurring from the 14th century onward."
