Thanks a lot for your advice.
The legend that I found about "ασκεω" and written on the site that I posted above has a long article about it. Site is a touristic Vietnamese company as I see from their business address. Might be made up I don't know. Here is the all article about the ασκεω legend as I don't want anybody to think that I want to direct traffic on their website.
"When, in may 334 b.C., the army of Alexander the Great passed the Dardanelle streits and started its march towards the heart of Asia, a young man coming from the cold valleys of the Great North was following that army, amongst the moltitudes of merchants, artisans, prostitutes, wine keepers and wagon builders. He wasn’t a man of war and although he was following that army he never grasped a weapon, but he became an expert craftsman, he learnt to ride horses and lead wagons, and the art of commerce, as well as revealing great culinary and canteen management capabilities. While Alexander’s army marched till the heart of Asia, in the camps his reputation grew as a man capable of many trades. There was no job he couldn’t do with great mastery, to the extent that the princes following Alexander turned to him to organize feasts and banquets, the transport of the concubines or of their own treasures, and to build large luxuriously furnished tents, to stock up with refined wines, to get hold of comfortable porters or fast horses. There was so much talk of his ability that the general Parmenione wanted to meet him. The old warrior, seeing him so young, asked him «what secret abilities has the god Hermes conceded you, so much so that you are able to execute with such mastery every task you are assigned?». The young barbarian, slightly taken aback, managed to answer only with one of the few greek words he had learnt, and said: «askew», meaning “ I work with care and diligence”. Parmenione liked his reply and said «from today you will be my First Intendant and since your barbarian name is unpronounceable for us Greeks, I would call you Askew, Askeo, and this will be the name of all your descendants». Askeo followed the army to the valley of the Indo and settled in the beautiful city of Taxila. He had a great descendance and all male first borns carried his name, Ascheo, and continued the activities of their ancestor....."
