I've created several memorials for individuals related to me as well as others both known and unknown to me as a way to help people locate the graves of friends or family. (Please note, the site is named Find a Grave for a reason.) I do not do it to track genealogical data for anyone other than those related to me. Unless I have done genealogical research on an individual and have documentation for it, I use the information made available on the memorial stones. If a memorial stone does not include a birth or death date, the middle name or initial of the deceased, their parents or children, or any other type of information, I obviously do not include it - and I have no intention of adding it for you. You may tell me what you want, but unless you can provide documentation for me I will not add it to a memorial. And if you do want me to add or change anything on a memorial and are not polite about it, you can absolutely forget about receiving any courtesy from me. In fact, as I recently did due to the rudeness of the Australian who belittled me for someone else's mistakes, I may go so far as to delete the memorial.
