Want to research your family history, but unsure of where to start or unwilling to splurge on an Ancestry.com account? On Saturday, the New England Historic Genealogical Society will offer a free orientation and tour of its facility, which houses more than 15 million artifacts, books, manuscripts, microfilms, journals, photographs, and records. You'll also be able to learn from the society's expert staff on how best to begin your family tree research, and use the organization's considerable resources to conduct research of your own after the tour concludes. (Saturday, Jan. 5, from 10 to 11 a.m.; New England Historic Genealogical Society, Boston; free; all ages)
If you're one of the many lucky people who got engaged during the holiday season, the Massachusetts Bridal and Wedding Expo is coming to Wilmington this weekend to satisfy your one-stop wedding shopping needs.

(Saturday, Jan. 5, and Sunday, Jan. 6, from 11 a.m. to 5 p.m.; Shriners Auditorium, Wilmington; $3 online, $15 at the door; all ages)
For a brief period in the late '90s and early 2000s, Ja Rule was a genuine hitmaker who provided gruff hooks to tender duets with the likes of Jennifer Lopez and Ashanti. While a lot has changed for the NYC emcee in recent years (Google "Fyre Festival" if you need a refresher), he can still belt out the hits, and will prove it at House of Blues this Saturday. Local hip-hop acts STL GLD, Billy Dean Thomas, and Cliff Notez will support as openers. (Saturday, Jan. 5, at 8 p.m.; House of Blues, Boston; $25-45; all ages)
It's been three years since the passing of David Bowie, and the musician's impact is still felt by many. To celebrate the late singer-songwriter, Bowie tribute band The Young Americans will perform a selection of the Thin White Duke's greatest hits at Thunder Road this Saturday. (Saturday, Jan. 5, at 9 p.m.; Thunder Road, Somerville; $8; 21+)
Clint Eastwood is still acting in movies at 88 years old, and doing a half decent job of it if reviews of "The Mule" are to be believed. If you want to treat yourself to a taste of the Eastwood of yesteryear instead, the Coolidge will be hosting a 35mm screening of "A Fistful of Dollars," which features Eastwood in his very first lead role. A lot has changed for Eastwood in the 55 years since "Dollars" helped launch him to stardom, but his effortless cool and piercing gray eyes remain. (Saturday, Jan. 5, from 11:59 p.m. to 2 a.m.; Coolidge Corner Theatre, Brookline; $12.75; rated R)
