I am looking for any information anyone might have regarding my great-great grandmother. I can't find any birth records and we only have a cemetary record and marriage certificate. I have pictures so I know she existed! She married my great-great grandfather David Arthur Day (son of William) in 1885. The marriage record shows her as 24 years old at the time and George and Samantha Day were witnesses. However in the 1900, 1910 and 1920 census records her name and age differs. She is then aka Louise Day, Isabella Day with her dob ranging from 9/1860 to 1869. She was said to have been born in Sanilac Twp and died in Tower, Cheboygan MI. The death record showed a Wm Smith as her father, mother unknown. I have tried EVERY name and date combination including the name Emma which my grandmother had mentioned a few times. I'm located in Florida so it makes it difficult. Can anyone please help???

Thanks so much!!
