The series comprises correspondence and papers relating to Labour Party organization in East Flintshire mainly during Eirene White's tenure of the constituency from 1950 to 1970, many deriving from the general election campaigns of 1950 to 1966. A few of the papers concern political life in the old Flintshire constituency, notably Eirene White's abortive candidature in the general election of July 1945.

Estate records, including deeds and documents, 1304-1887, relating to the estates of the Glynnes in Flintshire and elsewhere. The first three centuries covered by the deeds relate largely to the Ravenscroft family, their property, and their legal transactions. A large body of the documents relate to the period when Sir John Glynne, 6th bart., was the occupier of the estate. Other estate records include accounts, rentals, estate, household, and personal accounts, inventories, election expenses, colliery accounts, lists of charities distributed, estate maps, plans, surveys, bills, vouchers, etc., 1690-1872, including rentals of the lordship of Hawarden, 1686-1886. -- Amongst the personal papers are the diaries and account books of Sir John Glynne, 1753-1757, the diaries of the Rev. Stephen Glynne, 1798-1824, Mary Glynne, afterwards Lady Lyttelton, 1824-1831, Stephen Richard Glynne, 1825-1874, and W. H. Gladstone whilst at Eton College, 1856-1857; travel journals through North Wales, 1824, South Wales, 1824, Scotland, 1839, Germany, Italy, France, Spain, Switzerland, Belguim, Greece and Austria, 1834-1866, Turkey, 1848, Egypt, 1850, and Palestine, 1850. -- The archive also includes election papers such as lists of voters, canvass returns, accounts, relating to Flintshire elections, 1727-1837, letters written by and to members of the Glynne family and to Gladstone; notes on history, genealogy and ecclesiology; ships' log-books, 1727-1730 and 1734-1739. -- A separate group of legal papers which belonged to a lawyer named Dovey, relate mainly to bankrupts, and their immediate relevance to the Glynne family is not very obvious.
