So, in my digging, I have found out more information about my Ferdinand family members.
Joseph and Rebecca Ferdinand came over from Russia in 1891 and 1892 respectively. They married in 1893. They had six children - Morris, Samuel, Leo, Tillie, David and Emma. They lived in Chicago, IL and some moved to Peoria. Morris married a woman named Rae. Samuel married a woman named Florence. Leo married a woman named Lillian. David married a woman named Helen. Tillie got married but do not know to whom. I don't know if Emma ever got married. So if any of these names sound familiar to you, please email me at firstname.lastname@example.org
