• Ruth Mazo Karras, Sexuality in Medieval Europe: Doing Unto Others - a great intro to both sex in the Middle Ages, and how to talk about sex and gender in history
• Barbara Hanawalt, The Ties That Bound: Peasant Families in Medieval England - reconstructs family, living, and daily-schedule patterns for 14th century peasants based on archaeology and--wait for it--coroners' reports of accidental deaths
• Barbara Hanawalt, Growing Up in Medieval London - what it says on the tin
• Brian Catlos, Victors and Vaniquished: Christians and Muslims of Catalonia and Aragon, 1050-1300 - how did "Islamic Spain" become "Muslims living in Christian Spain," not on a military level but on a human-interaction one
• Olivia Remie Constable (ed.), Medieval Iberia: Readings from Christian, Muslim, and Jewish Sources - primary source excerpts in English translation. Fascinating and very large selection!
• Elisheva Baumgarten, Mothers and Children: Jewish Family Life in Medieval Europe - looks at childhood, parenting, and daily life among Jews in medieval Ashkenaz (France and the Rhineland) in comparison with Christians in the same area
• Oliva Remie Constable, Housing the Stranger in the Medieval Mediterranean World or Trade and Traders in Islamic Spain - crossover social/socio-economic history that considers Muslim-Christian and Muslim-Christian-Jewish interaction
• Julie Taylor, Muslims in Medieval Italy: The Colony at Lucera - Sicily's Muslim population was deported en masse to the Italian mainland; Taylor dives into what we know about the "colony" at Lucera and why the deportees stayed. (Alex Metcalfe has written on Sicilian Muslims more generally, but Taylor's book is a little less dense so I'd recommend starting there)

Hope this gives you someplace to start! :)
