Thank you for the links to familysearch.org. I am slowly going through the digital archives that are available there.

I have seen the entry on Poznan Project before. The surname of Raczkiewicz and Rutkowska are very different. Could it be the same person?

I have not been able to find out much about Walentyn Tobolski (born 1830) and his wife Agnieszka Raczkiewicz (1827-1893). Most of the entries I have found for them and their children (Władysław, Severyna, and Helena) have been in the Miłosław area. Are there any other databases I can search?
