Edmunds's granddaughter Elizabeth Withipoll married Leicester Devereux, 6th Viscount Hereford and the mansion passed to the Devereux family, who rebuilt the upper floors after a fire in about 1670, when the main porch was also added.[4] Claude Fonnereau bought the Christchurch estate in 1734 which at the time totaled more than 114 acres (46 ha) of land (today's park covers about 82 acres (33 ha)).[2] By 1772 the public were granted some access to the park and tried to introduce keys for those who would sign an agreement with conditions of entry.[2]
