Hi,
I am also doing a family tree on the Kozlowski's and I was wondering if they are of your relation? If they are it would be greatly appreciated if you could share any info you may have if you would have time. I would also be happy to share any info that would be of help to you that I may have. My Gr. Grandfather is Frank Kozlowski, his father is Joesph Kozlowski and so on.
Thanks.
