Do you know if Emily was a painter by any chance? I have an image of a portrait painted by an Elamine Deane in about 1905 of a person called Agnes Catherine Heath (nee Coussmaker). A John Coussmaker, Agnes's son, contracted her to make a copy of an original painting done in about 1794. John Coussmaker Heath was a general who reired from the Indian Army and lived in Bath. Both he and his wife are buried there. The family still has Emily's painting but the original is in the U.S.
I am a direct descendent of Agnes. If you want to find Emaline, you might consider looking in the India Office records housed in the British Library. My e-mail is email@example.com
