Welcome to the Radecki/Radeski/Radetzky Name Study Project!

How to Join

Please contact the project leader Alan Radecki or leave a comment at the foot of the page. If you have any questions, just ask. Thanks!


This is a One Name Study to collect together in one place everything about one surname and the variants of that name. The hope is that other researchers like you will join our study to help make it a valuable reference point for people studying lines that cross or intersect.

Task List

  1. Clean up existing Radecki/Radeski/Radetzky profiles that have been imported via Gedcoms, and add sources where possible.
  2. Comb through the Find a Grave database and add everyone with these last names. I've started, but with 455 Radeckis (not to mention the other spellings), this presents a daunting task, and I'd love the help anyone might offer.

Variations List

These variations have been found while researching this One Name Study:

  • Radeski
  • Radecke

A Migrational and Family Origins Study

As more and more names are being added to the Radecki Name Study, it's becoming clear that there are clusters of families scattered outside of Poland, where the name originated. Here's a list of locations of multiple generations of Radecki families, and the name and date of the immigrant who seems to have started each cluster.

Cluster Location Name of immigrant Date of arrival
Sydney, NSW, Australia Paul Radecki 1882
Stoughton, WI Joseph Radecki Bet 1902 & 1911
South Bend, IN Joseph Radecki July, 1912
Allegheny Co. PA Jan Radecki, Sr. Unknown
St. Paul, MN Walter Radecki? Unknown
Syracuse, NY Adam Radecki? Unknown

I am wondering if you have found any connection between Radecki surname and surname Radke, Radtke that exist in my family tree. These ancestors in my tree lived in Poznan area and migrated and settled in Wisconsin, USA in the 1800's. I am thinking the names sounds similar when spoken. Might be a connection somewhere.
