Adam Oliver was the husband of Mary Marshall. While living in Killinchy, Ireland, it appears eleven children were born to Adam and Mary.

Adam Oliver, listed as age 50, came from Ireland to America aboard the bark "Charter Oak" arriving in New York City, New York, 12 June 1848.

A ship manifest record for eldest son Adam has not been found. Son John did not come over until 1853, probably staying behind to wrap up affairs for the family in Ireland. Adam's wife, Mary, and six of his children arrived aboard the "Constitution" in 1849.

Adam Oliver "was a fisherman and boat-builder, and came to America in 1848 with his family, establishing his home near Rochester, New York. After coming to this country he engaged in farming on a small scale. In his family were five sons and four daughters, of whom two sons and three daughters are yet living: James, who is a wealthy farmer of Harrison township, Winnebago county, owning between three and four hundred acres of valuable land; Robert, of this review. Mary Jane, the wife of James Gilmore, of Rockford; Martha, who is the widow of William Miller, and resides in South Dakota; and Eliza, the wife of T. W. Allen, also living in South Dakota.
