[Janet Illian]

Looking for family of Kerstin Ersdotter and Olof Nilsson. Kerstin born 1815-02-05 in Stora Malke
and Olof born 1809-02-03 in Stora Mellosa.  
 
Kerstin's parents were Erik Ersson b. 1793 and Kerstin Persdotter b. 1793. They had 10 children.  
Erik's parents were Erik Persson and Karin Mansdotter. Kerstin Persdotter's parents were Jon Persson and Brita Andersdotter.
 
Kerstin Ersdotter and Olof Nilsson are my great great great grandparents. They had a child Christina Catherina Olsdotter b. 1838-06-13 Vastra Vinggakers. She married Lars Larsson b.1832-02-26 Stora Malm. They had 5 children, Gustaf Albert, Axel Henning, Elin Wilhemina and Mathilda Christina. Gustaf Albert is my great grandfather. Lars and Gustaf came to America in 1890's and died here. I have much more family information that goes back further. Please let me know.  
 
Thank You
