По поводу поляков, как и остальных славян в БТ - туговато им пришлось
Named after the first capital of the former Terran country of Poland, Poznan was colonized by refugees from Poland, Portugal, and Spain during the great exodus from Terra. This arid world is covered in jungles as well as harsh deserts. The planet's seven continents offered a variety of environments for the early colonists. The shattered and frozen Tortosa Badlands, for example, lie in Poznan's arctic circle. Two of the continents, Boleslaw and Mieszko, were located in the northern hemisphere and were settled by the Poles most because the continents resembled their former homeland. Boleslaw is larger and has more mountains. Mieszko has more flatlands and rolling hills, and has the largest freshwater lake on the planet, Lake Lednica. Both continents produce iron ore, petroleum, and various agricultural products.
By far the largest group of settlers colonizing Poznan were from Spain. They claimed the four largest continents, located mostly in the equatorial zone, naming them Barcelona, Palma, Seville, and Zaragoza. On Barcelona, the largest of the four, they set up the eventual planetary capital of New Madrid. Here they thrived and traded with their neighbors in the north and south. The refugees from Portugal settled on the island continent of Galicia. Galicia was rich in minerals, precious metals, and titanium ore.
During the next two centuries, Poznan flourished - but not without strife. A civil war was fought between the Poles and Spaniards over Palma. The war was ugly and brutal. The Spaniards won, and a planetary government was formed. Shortly after that war, they were offered membership into the Duchy of Liao in 2320. Over the next three hundred years, Poznan's population increased tenfold, with many of Chinese descent immigrating and pushing the Spaniards into the minority - and they were treated as such.

очень неплохой проект стратегической он-лайн игры + энциклопедия планет и описание их населения.
Думаю авторы сознательно пошли на асимиляцию старых национальностей и создание новых. При этом использование традиционных имен может также менять свой контекст.
Если мы говорим о Библейской традиции в современном мире наблюдается схожая тенденция. На пример, в современном Израиле в течение последних десятилетий наблюдается отход от традиционных имен - вместо этого используются производные от практически любых наименований растительного, животного (и тп) мира в Торе. В свою очередь Ветхозаветные "традиционные" имена не теряют своей популярности прежде всего в протестанской среде. Даже в "стабильном" европейском обществе имя далеко не всегда идентифицирует культурное, национальное или расовое происхождение его носителя. Тем более что законодательство предусматривает достаточно легкий процесс перехода с одного имени на другое.
