What is interesting about this story found below, is that Michael Koschnitzki's son-in-law Albert Lenser was born in Danzig, Germany. Albert Lenser and Augusta (Koschnitzki) Lenser also immigrated together to Pennsylvania, which means that they likely were living in or near the Danzig area together.  Albert Lenser also may have had Polish ancestry - his grandfather's name being Kupferschmidt (of unknown origin), and his grandmother's maiden name being Formella, which is of Polish origin.  It also notes that the last name can be spelled with either a Y or a I on the end, and be of the same family. 

ORIGIN OF THE FAMILY NAME KOSCHNITZKI - KOSCHNITZKY

The ancestral home was in Riga, Central Russia. In early days the name was spelled KUSNITZKY. The literal meaning is "hunters of bear and wolf".

During the time of the Tartar invasions (according to a Russian documentary film) a prominent General in the defending forces was General Kusnitzky. Under the reign of Peter the Great, members of the nobility, including the Kusnitzky group, formed a conspiracy to dethrone Peter the Great because of their hatred of his brutality. They were forced to flee. Some of them (including the forebears of Carl Frederich Koschnitzki) went to the Danzig (now Gdansk, Poland) area, and others fled to England, and later immigrated to Pennsylvania.

Carl Frederich told one of his granddaughters that at one time the family name had "von" in front of it, but changed it as he felt the name was long enough.

All the family background given to the granddaughter from Carl Frederich, was from an aunt he corresponded with who lived in Danzig (Gdansk, Poland).

Please bear in mind that there are various documents with two spellings of our family name; one with it ending in an "I" and also a "Y". Albert and Jonni (Jack) always spelled the name with an "i" on the end whereas John Wilhelm (Bill), Fritz (Fred) and August (Gus) always used the final "y". My grandfather's (Albert, Sr.) German Confirmation document shows an "I" whereas my Great Grandmother's (Anna Sophia)Memorial notice shows it with a "Y".

After living in the United States for some time, it became increasingly difficult for the family members to have people pronounce the name Koschnitzki/y correctly and also spell it. The name of KAY was legally adopted by most members of the family in the Superior Court of San Francisco, California on June 16, 1921 and on September 4, 1923.
The mother, Anna Sophia and son Fred (Fritz) decided to keep the family name of Koschnitzky.

(I am not sure if there is any connection between Michael Koschnitzki and the family below, however it is still interesting to note.)
