I saw "Beware of Greeks" yesterday, I am trying to figure who is known to be in Frasier's family. I have:

Noah: Martin's great-grandfather. Married to a Russian girl who brought a bear-shaped clock with her;

Aunt Louise: episode revolves around her funeral. Martin alternately calls her Aunt Louise and Louise, which hints that she might be from Hester's side of the family? Could be Hester's aunt, or even older sister as Martin says "Aunt Louise" to the boys.

Aunt Vivian: probably Martin's aunt, "Keeper of the Crane Family Skeletons."

Martin: Married to Hester and Ronee. Father of Frasier and Niles.
Eddie: Dog.
Frasier: Married to Nanette and then Lilith (who has a half-brother named Blaine). Father of Frederick.
Niles: Married to Maris (who has aunt Patrice and sister Brie, father was The Commodore), Mel, and Daphne (see below). Father of David.

Walt: Brother of Martin. Married to Zora. Father of Nikos.
Ed: guy with the video camera at the wedding. A couple of online scripts identify him as Martin's younger brother - is there any evidence of that?
Yvonne: "distant cousin" at the wedding who chased Niles.

Moon Family: Grammy Moon, Grampa who smoked cigars, uncle Jackie in San Francisco. Mother Gertrude, Father Harry. Brothers Michael, Simon, Stephen, Billy, Nigel, Peter, David.

Is there anyone else?
