We are looking for a descendant of Jacob Karpinski born about 1842 in Poland (Russia) and died about 1925 in USA married to Katherine Katalska. They had children between 1875-1892, some in Poland (Russia) and some in Allegheny, Maryland and some in South Dakota. The children in order of birth are: Michael, Josephine, Adam, Mary Katheryn, Joseph, Frank and John. I have reason to believe I am a great grandson of Kathryn Karpinski. I am looking for someone who descends from Jacob Karpinski to compare to my dna sample at familytreedna.com. This company has the capability to test any two people, male or female and compare their sample to see if they are related in up to 5 generations back on any line. If I can prove that I am a Karpinski descendant, I will know who my father probably is, as I was adopted in 1938. I would be willing to pay for the test to be taken. Thank you for your consideration
