2.  1860 Census Every-Name-Index/Images (online at Ancestry.com, Image #10 of 14):  Isle La Mott [Motte] P.O., Town of Isle La Mott [Motte], Grand Isle Co., VT, Roll M653_1318, p. 626, PN 56, 390/384, enumerated 7 Jul 1860, official enumeration date 1 Jun 1860 (extracted by Diana Gale Matthiesen):¤•

John Racy	32	M		Farmer		400	New York
Hannah "	32	F					Vermont
Madora "	5	F					"
Ruth Braggs	34	F					Vermont
Harmon Racy	25	M		Farmer			New York

There's a good chance that Ruth is Hannah's sister, but I couldn't find either Ruth or Hannah in the 1850 census.  "Harmon" is John's brother, Armon RACY.

3.  1870 Census Every-Name-Index/Images (online at Ancestry.com, Image #17 of 18):  Grand Isle P.O., Grand Isle, Grand Isle Co., VT, Roll M593_1621, p. 38A, PN 17, 126/135, enumerated  27 Jul 1870, official enumeration date 1 Jun 1870 (extracted by Diana Gale Matthiesen):(¤•)

Cootware William	22	M	W	Farm laborer	530	200	Vermont
Cootware Martha	34	F	W	Keeping house			Vermont
Racey Madorah	14	F	W	at home			New York

A file at WorldConnect shows that, despite the age difference, Martha is William's wife, and her maiden name is REED.

4.  1880 Census Every-Name-Index/Images (online at Ancestry.com):  Madorah not found, either as RACY/RACEY or as a married woman, at least not that I can recognize.
