The 7th Edition of the Canadian Genealogy Carnival has a Carousel (choose your own) theme. This carnival is always interesting even to those who may not have Canadian ancestors!
The 86th Edition of the Carnival of Genealogy was a "two-fer"; in other words, it had two themes: The "Other" December Events, and Our Wish Lists for Genea-Santa. There were 17 submissions for the first theme and 22 for the second.
The 19th Edition of the Smile for the Camera Carnival has been published at Shades of the Departed. With "The Gift" being a theme, there were a record-breaking 62 submissions! Wow! My own story, Christmas Gifts, was also written for the Advent Calendar of Christmas Memories, as were many other submissions.
As for upcoming carnivals, be on the lookout later this week for the Festival of Postcards (theme: White). Jessica is extending the deadline for the the 25th Edition of the Carnival of Central and Eastern European Genealogy (Christmas or Hanukkah Traditions) until December 28th, and submissions for the January 2010 Edition of the Graveyard Rabbits Carnival (Final Resting Place) are due December 25th.
Other holiday events include the Holiday 2009 Geneabloggers Cookbook (free) and the annual Blog Caroling Event hosted by the footnoteMaven. And Donna has republished "'Twas Just Days Before Christmas" to the amusement of all!
