Hi there Jenny. I am also researching a Caroline Auger born in Woolwich in 1863 to Henry and Elizabeth nee Watson.She had 3 sisters Adelaide Jemima b 9/4/1868 ,Anne 1/4/1870 and Clara 1874 all born in Islington. I believe there was a younger brother John too.
I am helping my sister in law with her fam history. Her grandma was Adelaide Auger,later Mutlow.
