Thank you to everybody who replied to my request. You have the correct family in 1891 and 1901. The reason that I though Gertrude might have been living at Girton College is because all the sisters left home after 1891, including my Grandmother Ada who was only 15 years in 1901 and I could not understand why she was not living at home as she was working in Cambridge. Also there is a mistrey as None of the sister who I knew plus my Grandmother never mention their brothers. It looks as though I shall never know if Gertrude did work at Girton college.
