The dates are off but I am sure this is the same family. It says Jacob came to America with his children Mary, Catherine, David (born 1847), Adam, and George Frederick. His son David and his wife Eva Margretha Ring had five children before they left Russia, they were Anna Kate, Elizabeth, Sophia, Jacob (this must be the Jacob who was just 2 years old)and Catherina then four more children were born after they arrived in America John David, Conrad, Effie, and Caroline. It says Jacob's father was Philip Spreier. So these bios are on the family of the son David and his wife Eva, not on the father Jacob Spreier.
