Hello all!

I'm a writer of several non-fiction books (including 'The Year of Living Biblically' and 'Drop Dead Healthy.' My current book, It's All Relative: Adventures Up and Down the World's Family Tree is about genealogy and tracing my roots. And for the finale of the book, I threw one of the largest family reunions in history.

Since we're all cousins, all seven billion members of the human family were welcome. Those who had a confirmed link to me received a special bracelet and were part of the record-breaking family photo.

It was exciting to use collaborative genealogy and WikiTree as part of this project. I had so many great volunteers working on my tree -- so thank you for that.

For more information on me and the start my project, here is a New York Times article I wrote when I first started this journey... http://www.nytimes.com/2014/02/01/opinion/sunday/are-you-my-cousin.html

And here's a link to my website page about it

Dear AJ,

Hope you get some great new information in the WikiTree Challenge 2021! I am on the team for CeCe Moore for next week. Should be very interesting. - NGP

Hi, In the profile for Michael Moos, Moos-33, Erna is linked as Michaels' father while Alfred is linked as his mother. Can you please swap Michael's parents to their normal mother and father relationship with him? Thanks.

Hi AJ I believe I may be distantly related through the Sparkman Jacobs line. Mabel Emilia Hawson is my grandmother Florence Coralie Hawson's sister. Mabel married George Kenneth Sparkman Jacobs who had Geraldine. Florence married William Michael Barry and their issue was: Patricia Mary Barry (my mother) who married Thomas Patrick Tobin; Jack "Jinx" Barry and Shirley Barry.

The Hawsons date back to 1761, The Tobins date back to the early 1800's; We named our daughter Andrea Jane Eblen and throughout her basketball career she was known as AJ. Cheers Jane Eblen

Well your Reunion book was released today - 7 Nov 2017.

But what I have read so far, is great. Mind you I am only up to chapter 12 so far.

Good luck with whatever the next book you have planned, and the adventures for that.

Happy Birthday Cousin!
We are related but I'd like to see a result via 23&me or Gedmatch.com..possibility of this? Your program is a BLESSING! Linked me to my Grandma's side just by a Wikitree profile update! Huge THANK YOU
