Hi. You might want to look in records of the Hundred Years War for references to the numerous Leslies who went to Germany to fight. The Leslies each had their men go, mainly as mercenaries. The purpose was to raise money to pay taxes. Alexander Leslie, son of George Leslie the Captain of Blair Castle, served throughout Germany under the Swedish king. He was joined by David Leslie. Both became generals in the cavalry. Alexander's son died in service. A son of the baron of Balquhain served under the Emperor of Austria and was rewarded for his services with land, titles, etc. Count Patrick Leslie furnished Fetternear with objects sent to him from Germany by Count Walter Leslie his uncle, Count James Leslie his brother and Count James Leslie his son according to 'Historical Records of the Leslies'. It also mentions that Count Anthony Leslie had family estates in Germany in the mid 1700s. They were not the first to serve in Germany. In the mid 1300s Sir Walter Leslie served the Emperor of Germany with distinction and on several trips was accompanied by a couple of his kinsmen.
