He was the eldest son of Christopher Rolleston of Watnall Hall by Anne, daughter of Captain Nicholas, Royal Navy. He married, firstly, Caroline, only daughter of Sir George Chetwynd, Baronet, by whom he had several children, and secondly, Eleanor Charlotte, daughter of Robert Fraser of Torbreck, Inverness-shire, by whom he had further children.[2]
He was appointed Colonel of the disembodied Royal Sherwood Foresters Militia on 11 April 1833, and retained the position when the regiment was reformed in 1852, when he commanded it during its initial training periods. It was embodied for home defence duties in the Crimean War and Indian Mutiny, although the command was exercised by younger officers.[2]
