Hello #GenHour, I am just landing back in New York following a work trip on the west coast. I had a great time.
Unfortunately, I haven't had much time for #genealogy research this week.

Hi #GenHour, I spoke with my distant cousin in France on Sunday. It went really well! She is around my age and is really interested in her family history. I shared with her information about our family history, which stretches back 500 years. Our video call lasted nearly 2 1/2 hours!

Not since 1935 has anyone experienced a storm like Melissa. Melissa's record wouldn't have happened without climate change, which made the hurricane's winds about 10 mph stronger, according to a rapid attribution analysis by Climate Central. yaleclimateconnections.org/2025/10/cata...

At landfall in western Jamaica, Melissa’s 185 mph winds and 892 mb pressure tied with the Labor Day Hurricane of 1935 in the Florida Keys as the strongest on record for the Atlantic.

It's getting tough to put into words how bad this looks for Jamaica. Here's my futile attempt this evening.
Melissa is now a rapidly intensifying hurricane, and it is plausible that it will produce an almost unimaginably bad outcome for Jamaica over the next 48 hours. Details below or at theeyewall.com.
Hurricane Melissa is rapidly intensifying southeast of Jamaica tonight
A devastating, catastrophic storm is expected in Jamaica, with torrential rain, flooding, and more for portions of Cuba, Haiti, and the Dominican Republic as well

Hi #GenHour, this is the big #geneticgenealogy news of the week. MyHeritage is transitioning to a low-coverage WGS test.
I may look to test again directly with MyHeritage if the results can help with resolving their imputation issues.
What are your thoughts?
