In the I884 edition of Debrett Col Hon George Molyneux, younger son of the 2nd Earl of Sefton, is said to have married a Mrs Eliza Stuart and had a son Charlie Berkekey Molyneux, who in turn married Emily daughter of the Rev John Meara and with two daughters had five sons! I cannot believe that some of these could not have left issue? However the above were totally omitted from later editions of reference books !
Whether because of illegitimacy I do not know?
