Kindly note that I do not accept the year of death minus the age as the correct year of birth because it does not take into account the number of months and days that had transpired since the deceased's last birthday. Most gravestones do not contain that information and to just subtract only the years of age from the date of death would be distorting information.

Example: Someone died March 28, 1934 at the age of 60 years, 3 months. Their gravestone did not give a date of birth, but contained an age of 60 which not take into account the months. A findagrave viewer who meant well thought that I should edit the memorial to show that the deceased was born in 1874. This would have been adding incorrect information because if someone died in March 1934 at the age of 60 years, 3 months, in actuality they would have been born in Dec. 1873.

I also do not accept the month and year of birth in the 1900 United States census or the age in any census as accurate proof of date of birth. A census is a census and a birth record is a birth record and never the twain shall meet. Then and now no one was ever required to provide proof of date of birth for a census. A person could have given any age they wanted.

Case in point:

My grandmother was listed as age 7 in 1887 Lithuanian census list (meaning she was born in 1880)
She was listed as being born in October 1880 in 1900 US census
She was listed as age 33 in 1910 US census (meaning she was born in 1877)
She was listed as age 34 in 1915 New York State census (meaning she was born in 1881)
She was listed as age 39 in 1920 US census (meaning she was born in 1881)
She was listed as age 43 in 1925 New York State census (meaning she was born in 1882)
She was listed as age 48 in 1930 US census (meaning she was born in 1882)
She was listed as age 59 in 1940 US census (meaning she was born in 1881)
She was listed as age 61 on her Oct. 12, 1941 death certificate (meaning she was born in 1880)
She was listed as age 62 on her gravestone (meaning she was born in 1879)

Have I made my point?

The bottom line is that a birth record is the only accurate proof of date of birth. If a gravestone does not contain a year of birth and lists just an age, let it go as is unless you can provide proof of exact date of birth. Otherwise you are corrupting the data.
