Etimoloxía (Inglés)

From Middle French martingale, from Occitan martegalo, feminine form of martegal, an inhabitant of Martigues, which is from Latin maritima. Alternatively from Spanish almártaga.
The meaning in gambling may come from an old usage of "à la martingale" to mean absurdly, foolishly.https://people.math.harvard.edu/~ctm/home/text/class/sem/html/home/notes/martingales/martingales.pdf
