The Southington Genealogical Society will present a program on X-DNA research Tuesday, Oct. 28.

Robin Michel, on behalf of the Southington Genealogical Society, said the program will be held in-person at 6:30 p.m. at the Southington Historical Society at 239 Main St. A Zoom option will also be available. The program will feature X-DNA expert Mary Beth Krafcik.

“Krafcik’s presentation on X-DNA was initially written for a family newsletter and revised for publication in both the Italian Genealogical Society of America and Italian Genealogical Group newsletters,” Michel said. “It represents years of original research pulled from numerous sources and will be presented in this format.”

The program will include a description of the biology of X-DNA and information about X-DNA recombination, X-DNA inheritance patterns, X-DNA inactivation and how to use X-DNA in genealogy research. Krafcik will also include examples from her own X-DNA.

Michel said Krafcik, a former long-time resident of Southington, has roots in the U.S. which extend back to the beginning of the 20th century.

“While researching her ancestry in Italy and Slovakia, she became interested in DNA and its applications in genealogy research,” Michel said.

Krafcik is a former board member of the Italian Genealogical Society of America and a member of the Italian Genealogical Group. She has contributed articles to the newsletters of both groups.

“Her IGG newsletter articles on ‘Affinity’ and ‘How I Found a 6th Great-Grandfather Using the Antenati Website’ were among those reviewed by the National Genealogical Society for its 2025 Large Society Newsletter award,” Michel said.

Michel added that one of Krafcik’s interests in future research is the immigration patterns of ancestors to America at the beginning of the 20th century and how residents of Southington are related to each other.

The Southington Genealogical Society Inc., founded in 1984, is a nonprofit organization that promotes the accurate recording, research and preservation of family history. The organization meets monthly on the fourth Tuesday of the month at 7 p.m. at the Southington Historical Society.
