The daughter of Imperial Court Chancellor Count Theodor Heinrich von Strattmann und Peuerbach, she was married to Hungarian nobleman and Ban of Croatia Ádám II Batthyány until his early death in 1703.

[3] In 1685 Theodor von Strattman was raised to the rank of count by Emperor Leopold I and appointed Austrian court chancellor, the functional Habsburg foreign minister.

Count Ádám II Batthyány came from Németújvár in the frontier region of Austria and the Kingdom of Hungary, after he had rendered outstanding and valuable military service to Emperor Leopold I, most notably during the Siege of Stuhlweissenberg and the Siege of Buda in 1686 where he fought alongside a young Prince Eugene; in 1693 Adam became Ban of Croatia[4] and was rewarded with the Bóly Estate in the year 1700.

[5] After Adam died at a young age on 26 August 1703, Eleonore, who survived her husband for almost 40 years, look after the extensive Batthyány property and took over the guardianship of their two sons Ludwig Ernst (b.1696) and Karl Josef (b.1697).

[6] The Stranmann Palace was built by the famous Baroque master builder Johann Bernhard Fischer von Erlau, her father's estates, after his death, were merged with those of the Batthyány family.

This "grande dame" organised elegant soirees and assemblies, as the evening parties were called at the time, in her palace on Schenkenstrasse, today's Bankgasse in Vienna.

[12] It is not known precisely when their relationship began, but his acquisition of a property in Hungary after the Battle of Zenta, near Eleonore's Rechnitz Castle, made them neighbours.
