dana, you should talk to the findagrave people and see if you can take over that listing for your ancestor on findagrave.
usually, the only way a child is listed on a memorial is if someone knows where the findagrave listing for that child is located. many times it is because the child is buried in the same area, perhaps a family plot. if you know where more children might be buried, it would be worth listing them as children on that webpage and linking to their findagrave listing.
also, many findagrave contributors are not related to their listings and many do not pursue the obituaries themselves. rather, they are usually people who live near a cemetery and have walked the cemetery and listed the occupants of the graves. in my opinion, you should see if an obituary is available from historical newspapers and post it on the findagrave webpage for that person.
findagrave contributors will usually post an obituary, if the family gives the contributor a copy of it.
i have also found that many contributors will not allow family to replace them as the contributor. apparently, many contributors want to be listed for as many findagrave pages as they can get and that does not work in favor of actual family members of that person. worse, findagrave takes no position on this and will not change the contributor to a family member. however, if a contributor is deceased, then you might be able to prevail on findagrave to change the contributor to yourself or another family member because that person’s memorial page is now not being maintained.
for an obituary, you should contact your local public library/interlibrary loan program. the obituary might be available through the library, through local historical societies or state archives.
some people post death certificate information, family members. i am of the opinion that more information is better, so that others can find your family members.
