Don’t put off writing up that genealogy information until you “get around to it,” “until life slows down,” or “until you have it all completely done.” Many times the ideal point in life to write up that family history never arrives and it certainly doesn’t knock on your door and announcing “I’m the perfect time to complete that family history project.”
Something is better than nothing. At the very least share those identified pictures. Someone in 100 years may treasure your incomplete project than you imagined and certain cannot treasure what you never even started.
If you’re looking to buy DNA test kits, AncestryDNA is offering some sales until this coming Father’s Day (19 June 2022). Just remind the testee that there may be some unexpected discoveries. Some people welcome those. Others do not.
