Charles Henry Roberts was born in
Pedmore,
Worcestershire, the son of Charles Roberts and Marianne (née Noble). His father was a descendant of William Roberts, who had been responsible for rebuilding
Drybridge House, Monmouth, as the family's home in the late 17th century. In 1861, Charles Henry Roberts married Mary Crompton, an only child and heiress from
Breightmet, near
Bolton,
Lancashire. He sought and received royal assent to add the name of Crompton to his own surname, so enabling him to inherit her family's estates. Crompton-Roberts acquired Drybridge House in 1867, and carried out its restoration and enlargement. While retaining the period features of the existing building, he added a new south wing and commissioned a number of stained glass windows. He also designed a fine parkland garden around the house, incorporating a cricket pitch upon which
W. G. Grace later played. Another family friend was
Edward Elgar, who married one of Charles' Worcestershire cousins,
Alice Roberts. Crompton-Roberts purchased land at
Trellech Grange from the
Duke of Beaufort in 1875, and was appointed
High Sheriff of Monmouthshire in 1877. He continued to contribute financially to the amenities of Monmouth, and was responsible for the reconstruction in 1888 of the mediaeval
Cross opposite the
Church of St Thomas in
Overmonnow, near Drybridge House. He also decorated houses in Drybridge Street, and his own summer houses, with large wooden blocks used in the hand printing of
wallpaper. At the time of his death he held the positions of Governor of
Monmouth School and Monmouthshire County
Magistrate, and represented the Borough on Monmouthshire County Council. He was also reported to be sole proprietor of the varnish manufacturing firm Noble and Hoare, of Cornwall Road,
Lambeth. ==Death and memorials==
