Seattle Genealogical Society (SGS) vice president Janice Lovelace will give a presentation for genealogy researchers on how to research ancestors that were slaves from 1 p.m. to 3 p.m. Saturday, Feb. 25 at The Seattle Public Library, Central Library, 1000 Fourth Ave., Level 4, Howard S. Wright Family & Janet W. Ketcham Meeting Room 2, 206-386-4636.

Library events are free and open to the public. Registration is not required. Parking is available in the Central Library garage for $7.

Many African-American genealogical researchers struggle to break through the brick wall of slavery. In this presentation, Lovelace will demonstrate techniques to identify emancipated slaves and their prior slave-owners through the use of land, probate, census and court records.

Alongside her academic genealogical credentials, Lovelace has 20 years of experience in family history research. A member of SGS for a number of years, she joined the SGS board as vice president in 2014. Lovelace is also a member of the Association of Professional Genealogists and National Genealogical Society.
