I am Samuel Berry's great grand-daughter. His son, Eugene Samuel b 1913 was my grandfather. In general, most of your research is accurate. Eugene and Florence were sent away to an orphanage to live after Alvina died. Samuel married Margaret, but the two did not want to have the first two kids living with them. They lived a very lonely and difficult life in the orphanage. My grandfather said that when he was later reunited with his family as a child and his aunt set him on his lap and hugged him, he felt like he had gone to heaven because he had never known affection.
I have a facebook page with many photos of Samuel's father's family in Oscoda, MI.
