Count Eugen Reventlow (1798-1885) and Count Theodor Reventlow (1801-1873) were the children of Danish diplomat and noble Cay Friedrich Reventlow. Eugen was appointed Secretary to the Danish Legation in St. Petersburg in 1823. He remained there until his brother Theodor assumed the position in 1828. As Eleanor Middleton succumbed to illness in 1827, her diary entries likely refer to the elder Reventlow. The portrait in the Album however may be of either brother.
The bust-length portrait presents Count Reventlow facing partly left, eyes looking forward, against a background of grey clouds. The young man wears a blue-black coat with gold buttons, a beige waistcoat, and a white shirt with a black cravat.
Ballegård er en hovedgård på Sundeved, beliggende ca 2 km øst for Blans i Ullerup Sogn, Nybøl Herred, Sønderborg Kommune. Den to etagers hvidkalkede hovedbygning i rokokostil er opført 1771 ved Lorentz Jacobsen og fredet tillige med to andre mindre huse i 1950. Senere kom gården i Conrad Reventlows eje. Han fik kongens tilladelse til at oprette Grevskabet Reventlow med hovedgårdene Sandbjerg og Ballegård. Gården er beliggende ved et lille vandløb, som drev en mølle, som der stadig kan ses ruinrester af. Navnet "Ballegård" kommer sandsynligvis fra gårdens beliggenhed på en mindre forhøjning (balg, balle).
