Ok census links are now working. We have a mystery here... Cythia spelled Synthe in the census is listed as married to David a farmer born in Tennessee. His Father is listed as born in South Carolina and his mother as born in Tennessee. No names for his parents are listed. He is listed as age 47. The David is written in such a way it almost looks like Xama so transcriptions for this family may be difficult to find.
Synthe is listed as age 38 born in North Carolina. Her parents are both listed as born in North Carolina and no names are listed for them.
Siblings: James C age 13 works on the farm
(the above from 1880 Federal US Census page 13, supervisor dist 8, enumeration dist 120, Rich Precinct, Union, Illinois, taken June 29, 1880.
Now on page 14:name is for a female and it looks like Adievillet age 12
Jeannette age 10
Sarah age 8 (so her birthday must be before June 29 or she would be 7 in the Census if the person giving the info is correct)
Jefferson age 5
Martha age 11 months born in July the year before.
All children are born in Illinois.
Most of 1890 census has been destroyed by fire and flood
