My grandfather (OR6-G8Q1-GBDJ) was identified as female in the 1880 census. “Female” is how I entered his gender into Rootsfinder.
The 1900, 1910, and 1920 census show him as male. For these years, “Male” is how I entered his gender into Rootsfinder.
Despite the contrary information in 1900, 1910, and 1920, RootsFinder continued to show only Gender Female in the timeline.
I attempted to patch things up by doing edits under 4. People. This helped, but Gender Female still shows in the timeline, citing the 1910 and 1920 census as sources.
It seems as though RootsFinder uses the first entered (or maybe earliest) event to assign gender and then sticks with that, even when subsequent information is different.
