Guy's mother was a daughter of Henri de La Tour d'Auvergne and sister of the Marshal Turenne.

Guy was one of 12 siblings: In the Franco-Dutch War (1672–1678) Lorges served mostly under Turenne in the French Rhine Army.

On 4 October 1674 in the Battle of Entzheim, Lorges commanded the Brigade d'Humières and the Dragons de la Reine on the left wing.

[24] The army retreated from Sasbach and fought the Battle of Altenheim, where Vaubrun, who commanded the rearguard, was killed on 1 August 1675.

When Lorges arrived back in Alsace he was ordered to hand over the command of the Rhine army to his brother the Duke of Duras, who had come from the Franche-Comté for that purpose[25] while waiting for the arrival of Condé from Flanders whom Louis XIV had appointed as commander of the Rhine Army.

[26] On 26 January 1679 France made peace with the Holy Roman Empire in the Treaties of Nijmegen ending the Franco-Dutch War.

[27] On 19 March 1676 (date of the contract) Lorges married Geneviève de Frémont, daughter of the keeper of the King's jewels.

Guy Aldonce and Geneviève had one son and four daughters: Saint-Simon praised Lorges, his father-in-law, warmly in his Memoirs, describing him as highly principled, frank, upright, good-natured, sincere and the most truthful man alive.

[37] Lorges supplied his son-in-law with useful material for his memoirs, particularly on the early relations between Louis XIV and Madame de Maintenon.

[40] On 27 September 1692, he surprised and routed 4,000 imperial cavalry under the command of Frederick Charles of Württemberg-Winnental in their camp at Ötisheim and took Württemberg prisoner.
