She and her son Walter are living with her brother in 1850 census, listed as Loama White, following a divorce or the death of her husband Denison. She is listed as not being able to read and write.
Then listed as Loama Fellows (47, VT) with the family of her daughter Esther and husband Anson Hill in 1860, just after their marriage. This makes it appear that Loama was remarried. There is also an Alice Cook (3, NY) listed with the family, possibly an illegitimate daughter of Esther, before her marriage.
She is then listed as Loamy White (60, VT) with her son Marshall and wife in 1870.
Living with her daughter Ester and husband Anson Hill in 1875 and 1880 census. In 1880 she shows up as Loamy Hill (67, VT), probably in error, since everyone else listed has the Hill surname.
Her cemetery record lists her name as Loamy.
