Duke, who led the squad in Israel last summer at the 20th Maccabiah Games, will be joined by assistant-manager Hollie Geey and coach Gabriel John.
He said: “Having been involved in Jewish football since the age of 14, I am both honoured and excited with the appointment.
“Together with Hollie and Gabe, we are looking forward to building on last summer’s Maccabiah and hopefully come home with a medal.”
Geey first represented MGB aged 13 at the JCC Maccabi Games. She featured in the playing squads at both the 2011 EMG in Vienna and the Maccabiah last summer in Israel.
