Menashe (Max) Kadetsky and Berko (Benjamin) Kadetsky

I have been mystified about the connection between Benjamin Kadetsky b. 1870 who lived in Buffalo, NY and other Kadetsky who lived there including Friedman Kadetsky b.1862, Chaia (b. 1878) and Gersz (b.1877) Grabkowitz/Gary, and Max Kadet (b. 1883/1880). Over the weekend I was looking at Ancestry's immigration records and came across the Ellis Island Manifest for Menashe Kadetsky who arrived 1/2/1904 on the St. Louis and joined his Uncle Berko Kadetsky at 259 Main St. in Buffalo, NY. According to multiple business records that can be found doing a google search using keywords Kadetsky Buffalo NY, it is documented that Benjamin B. Kadetsky owned a tailoring company at that address. Jenni Hymoff had documented this manifest years ago, I have just rediscovered it now. This is the first document that connects Benjamin Kadetsky to anyone but his immediate family! I have not yet found a record to indicate exactly who Menashe Kadetsky is, but there is a Max Kadet, the brother of Chaia Grabkowitz, Mendel Kadet, Benjamin (a different Benjamin from the subject of this post), and Aaron Kadet who lived in Buffalo as well. (Much info about this family can be found by searching for the surname Kadet on findagrave.com) I have never found his Ellis Island manifest, but I strongly believe that Max Kadet and Menashe Kadetsky are the same person due to proximity of birth years and that in the 1930 census Max Kadet is listed as immigrated in 1903. Based on this relationship, Benjamin Kadetsky is the brother of Friedman Kadetsky and Sussman Kadetsky among others including Abram Icek Kadecki, Perla Kadetsky, and Hyman (Chaim) Kadetsky. Retrospectively, I see that when Chaya Grabkovitz immigrated she stayed at at Hersz Grabkowitz at 257 Main Str in Buffalo, the address of Benjamin Kadetsky's business.

He served as the synagogue president in Buffalo for congregation Ahavath Scholem.

Here is Benjamin Kadetsky's Ellis Island manifest from 11/30/1886, that lists his home town as Sierpc. According to Benjamin Kadetsky's passport application from 1910 his was bron in Shirtz, Poland and immigrated on 11/1885.
