The name likely emerged as a nickname or a descriptive name for someone who was associated with or had some connection to Troy or the Trojan legend.

One of the earliest recorded instances of the name Trojanowski can be found in the Metryka Koronna, a collection of records from the Crown Chancery of the Polish-Lithuanian Commonwealth, dating back to the 16th century. This suggests that the name had already gained prominence and usage by that time.

Some notable individuals bearing this surname during this period include Jan Trojanowski, a Polish nobleman and military commander who fought in the Polish-Swedish Wars of the mid-17th century.

The 19th century saw the emergence of several prominent individuals with the Trojanowski surname. One such figure was Kazimierz Trojanowski (1828-1891), a Polish historian and writer who authored several books on the history of Poland and its culture.

Another notable Trojanowski from this era was Stanisław Trojanowski (1837-1905), a Polish painter and art professor who contributed significantly to the development of Polish academic painting and art education.

In the early 20th century, the name Trojanowski gained further recognition with the birth of Tadeusz Trojanowski (1901-1983), a Polish military officer and diplomat who served as the Polish ambassador to the United States during World War II.

The Trojanowski surname has also been associated with several place names in Poland, such as the village of Trojanowice in the Silesian Voivodeship, which likely derived its name from the Trojanowski family.
