CC 28.5.1801 at Sadler's Wells / 11.6.1803 wet docks & beasts in tower with C C / 30.6.1803 C C / 27.8.1803 C C at Lamb's / 21.4.1804 C C / 17.12.1807 theatre, w. T(homas) T(urner), F(anny), C(harles) & M(ary)
Careful study will convince you that these all referred to Charles Clairmont (born 1795) who was usually noted as C when with several other children all with a single initial. The GD website has left them uncoded, even though it has coded later examples of C C to him. One C C that wasn't him was 23.2.1804 Golden Cross C C where Godwin and his brother Joseph boarded the coach for Lewes, and C C must have been short for Charing Cross
25.7.1801 tea Clts, mirza
Should be coded in GD website to Mary Jane Godwin. Mirza is explained in Wm St Clair, The Godwins & The Shelleys
