HCR diary 30.11.1841 called "on Mrs De Morgan about Mrs Aders. I found her impression unfavorable - and even Mrs Gilman it seems is less friendly - perhaps it may be she is tired out. She said she thought I had been too kind"
Probably Sophia Elizabeth (1809-1842) wife of Augustus De Morgan (DNB 1806-1871) and daughter of William Frend (DNB 1757-1841). They married on 3.8.1837 and had seven children
