She left her own room and slept with me. One kiss last night. Breakfast at 11¾. Came up to my room at 12¼. Wrote 3 pages & the ends to my aunt, ditto to Mariana, ditto to Mrs Barlow & very nearly 3 pages to my sister, & 1½ page to Mrs Duffin, which took me till 4½. Dress for dinner. Dinner at 5. Lieutenant Colonel McNeil of Barra here, a very gentlemanly man just on ½ pay from the lifeguards. Come to look for a house in Mull. Barra too far off. From 8 to 9 p.m. walk out with Mrs & Mrs McLean & Breadalbane  about the garden grounds. Beautiful bay. Beautiful little freshwater lake. Beautiful situation for a house. Tea. Afterwards strawberries & cream. Came to my room at 10¾. Very fine day. Said, in walking, they really ought to call the house Coll House. No objection. Agreed. Should be [written] Drimfin (dreemfin) the hill of Fingal.
 Breadalbane (AKA Albane) was Sibella’s youngest sister. Sibella had one brother, Hugh (the eldest of the siblings) and 5 sisters: Janet, Catherine, Marion, Maria and Breadalbane (See p.382 Alexander Maclean Sinclair, The Clan Gillean 1899 Haszard and Moore, http://www.archive.org/stream/clangilleanwithp00sinc#page/382/mode/2up).
Sibella’s sister Janet married George Vere Hobart and they had one daughter, Vere Hobart. Anne Lister met Vere in 1829, travelled with her in Europe and set up house with her in Hastings in from October 1831 until April 1832. Anne had hoped to persuade Vere to marry her, but was sorely disappointed when Vere announced her engagement to Donald Cameron. Vere is the woman in whose lap Anne is weeping in at the beginning of the TV show Gentleman Jack.
