The identity of his first wife is unknown. His second wife was Lithuise de Blois, Vicomtesse de Troyes, daughter of William Busac, Count of Soissons (c. 1084–1118).

Milo and Lithuise had at least nine children: Guy III Trousseau, lord of Montlhéry Thibaut Milo II (died 1118), lord of Montlhéry and Bray-sur-Seine, viscount of Troyes Adelaide Elizabeth (Isabella) of Montlhéry, married Thibaut of Dampierre. Their son was Guy I of Dampierre.

Milo joined the Lombard contingent during the second wave of the First Crusade around 1100 together with his brother Guy II. He returned from the crusade "broken by the stress" and "devoid of all bodily strength".
