I only have day/month dates for some relatives births, but no year. I usually record them as "25 Dec 19_" leaving underscores for the last two digits. The problem is the Brothers Keeper software I use assumes the year 19_ is the year 19 A.D. So if I upload a gedcom to Ancestry.com, these living people are designated as dead, and all their info will be shown.
Is there a way to fool the Ancestry.com "living/non-living" detector? Will "25 Dec 19??" work, or a fake future date, like "25 Dec 9999" ?
