The Osbaldestons were lords of the manor of Osbaldeston from the 11th century. The last members of the family to hold the estate, Edward and his son, Alexander, were related to Lawrence Rawstorne and the family appears occasionally in the diaries of Rawstorne and Thomas Bellingham. Edward Osbaldeston was aged 12 in 1664. He married Margaret, the daughter of Thomas Braddyll of Portfield in 1676 and died in 1689. He was succeeded by his son, Alexander, who was born in 1677 and died in 1747. VCH says that the ‘decay of the family was due to the profligacy and ill-judged generosity of Alexander’, who mortgaged most of the family estate. Living for most of his life in Preston, Alexander apparently did not marry, instead, to judge by entries in the Tyldesley diaries, enjoying a merry bachelor life in the town.
