Remember that it is entirely possible that a list of grandchildren in an obituary may list grandchildren who are actually step-children of a child of the deceased who is no longer married to the spouse from whom they acquired the step-child. If the grandparents considered their child’s step-child their grandchild, that relationship and consideration may not have ended when their child’s marriage to the parent of the step-child ended. While these relationships may matter greatly to the individuals involved, DNA is only concerned about which individuals reproduced with which individuals.
Many documents and records that genealogists use contain information that is submitted or given without any attempt made to validate the information. Always ask yourself, is there a chance the informant was misinformed, guessing, lying, or in some other way giving incorrect information that would never be fact-checked by the clerk or contain information whose inaccuracy would later be discovered?
