Hi
in 1871 Sophia is now listed as SOPHIA F SAUNDERS , THE children are listed as
REES SAUNDERS, JAMES SAUNDERS & what has been transcribed by ancestry as FROST SAUNDERS aged 13 ( looking at the actual census, i see why ?), this could be FRED, and Emily saunders who was born abt 1866
looks like hey changed the surname from Freeman to Saunders
