My great grandmother was Clara Firstner born in St. Mary's, Ohio. Her mother was Fredericka Rosenow. I do not know who her father is. I only know that they were supposedly both from Germany.Clara had a few brothers, who moved to Buffalo, NY... and Clara had moved to Dunkirk, NY before 1910. In the 1900 federal census, Clara is Married to my great grandfather Wilhelm Rudolph and living with a few of their kids in Eden, NY with Fredericka living with them. Any other information about Fredericka or her husband would be awesome!!
