Hello, I've posted the result of work on Ostrowski families and related individuals that were in the Detroit, Michigan area.  This information is based on the Detroit city directories, US census records, and Michigan vital records on FamilySearchLabs. A good page to start is in the name index, but everything is linkable: http://www.dealraider.com/gene/detroitostrowskis/names16.html If you had any Detroit-area Ostrowskis, please take a look and see if you link in or know any more information on these families.  Please send me an email here or through the site with any information updates you have.  If you have any information that would prove that some of these people are duplicates of each other, I'd be grateful. I did this work because I'm trying to find the ancestral village of my ancestor Vincent Ostrowski (1860-1939).  By surveying all the Ostrowskis in the area, I hoped to link together with some other families who may be easier to trace the ancestral village.  After all this effort, I have not been able to accomplish that yet, but the work is hopefully useful to everyone else. Thank You! p.s. I'm primarily looking for my ancestral village in Poland (West Prussia) of Vincent Ostrowski (b 1860 - d 1939, married to Julia Radzikowska).  After a lot of work, my best hint is still the Hamburg Passenger List that gives a town that looks like Kl. Conja, but I have not found a matching record yet on any towns.  If you have any information, please contact me, I also have a big reward for anyone that prove the original village! :)
