During the 1841 election campaign, Glynne found himself obliged to start libel proceedings against the Chester Chronicle for having published allegations of homosexuality against him.

[10] William Gladstone frequently consulted Glynne on ecclesiastical matters, including, for example the appointment of a Welsh-speaking bishop, Joshua Hughes, to the diocese of St Asaph in 1870.

Archdeacon D. R. Thomas wrote: "Those who had the pleasure of his acquaintance will remember how complete and accurate were the details that he could so readily call to mind, and that an extraordinary memory underlay his quiet and unassuming manner.

[17][18] He spent several months of each year on this activity, travelling by rail, horse-drawn transport, boat and on foot, and staying at hotels, inns and guest houses.

[19][20] In keeping with the principles of the Ecclesiological Society and the Oxford Movement, he was a devotee of the Gothic style of architecture, and was damning of 18th-century classicism, and of fittings such as box pews and galleries.

His manuscript notes, dating from 1824 until a few days before his death, cover churches in England, Wales and the Channel Islands, and a few in Scotland and Ireland.

[21][22] His notes are greatly valued by architectural historians, as they frequently provide a brief but informed record of the buildings as they were before Victorian restorations and re-orderings.

[23] Glynne also toured widely in Europe and Turkey, keeping detailed diaries, but here he showed considerably less insight, and his notes are considered to be of far less interest than his British material.

[25][26] He was buried in St Deiniol's Church, Hawarden, where he is commemorated by a recumbent effigy by Matthew Noble in a tomb recess designed by John Douglas.
