Her mother must have missed her terribly. Sarah's husband dies soon after in 1912 in May the day after Sarah's 39th birthday. Sarah dies in 1955 at the age of 81 yrs and 11 months, after about 43 yrs of apparent widowhood. It must have been a very lonely life for her. This is only conjecture, but seems quite possible from the headstones.
