Seeking any information on Margaret Appleton, wife of Edwin E. Appleton of Nevada County.

Would anyone happen to know her date of death, or any other information about her?

So far, my research shows she may have previously been Margaret Kennedy and that she married E. E. Appleton on May 1, 1867 in Nevada County. She may have died sometime prior to May 22, 1870 as I have found Edwin E. being married to Ann Irving on that date.

Also have found the following:

E. E. Appleton who was a resident of Washington and was listed as in the refinery business in 1879.

The obituary of E. E. Appleton, b. England 1831, ex-Chief of the Grass Valley Fire Dept., member of AOUW. He died in Grass Valley 18 Apr. 1894, leaving a wife 3 girls and a boy.

The obituary of Ann Appleton, native of New York who came to California when an infant in 1852, died at 78 yrs. in Sacramento June 3, 1931. She was a charter member of Olympic Temple, No. 10, Pythian Sisters of Grass Valley; Sacramento Pocahontas and Rebekahs. Although she had lived in Sacramento many years prior to her death, she was considered an old time resident of this community. She is stated in this obit to have been the widow of the late Edward Appleton. Surviving her were: three daughters, Mrs. Margaret Hurley, Mrs. Edith Rowe and Mrs. Etta Snyder of Sacramento; one son, Edward Appleton of Sacramento and the following brothers and sisters: Mrs. Sarah Mullins, Grass Valley; Mrs. Elizabeth Gummoe, Oakland; Mrs. Dottie Skibinski, Oakland; Mrs. Kate Beardsely, Spokane, Washington; Robert Irving, Crane, Oregon, and John Irving, Sacramento. It was said that her remains were to be brought to Grass Valley for burial in the City Cemetery.

Would anyone happen to know if E. E.; Edwin; and Edward were as I suspect the same individual and/or have any more information pertaining to this family?
