Hello,
Do you know when Herman/Oscar was born? He isn't listed in the birth records, but, there is a Samuel Wilhelm born 13.9.1842, to Samuel Wilhelm Berg and Lisa, in Pattijoki Village. Also, an Anna Lisa was born 11.8.1845 to Samuel Wilhelm Bergh, aka Perälä, and Lisa in Pattijoki....I also found that Samuel Wilhelm Berg married Lisa Henriksdotter Perälä 13.6.1840 in Pattijoki.....And, there is a Johan Henrik born 17.9.1840 to Samuel Perälä and Lisa in Pattijoki....So, could he be the brother Johan H., of Herman/Oscar? The records stop at the year 1850, so, if Herman/Oscar was born after that......If his wife was from Pattijoki, I found that a Fanny was born out-of-wedlock 10.7.1840, to Harriet Vilkinson.... this may seem confusing, but back in the day, surnames of the wife were used...therefore, Berg and Perälä were recorded...making it very difficult for us who are trying to find information. I hope this may help you.
