I have Thomas Killebrew 1880 married to this third wife Martha Ann Henderson 1824 to 1878. They had a daughter Susan b. 1869. The Hendersons and Killebrew's lived on the same farm, believe it to be the Killebrew farm because the Killebrew's are listed first in the 1980 censua and that is the usual way. The Hendersons's were William Jasper Henderson m. to Sarah Elizabeth Killebrew. The Hendersons had 6 children at the time of the 1880 census, I will have to go to my files to find if they had more. The Killebrew is English and the name is from Cornell England, The first Killebrew's came over with the name of KILLEGREW.All the papers I have from William shows he used the name KILLEBREW, when he died, his wife Sarah paid her taxes under the name of KILLEGREW. Two of his sons were married under the name of KILLEGREW.I have a history of the Killebrew name and will send it to you if you wish and can take an attachment.
