patrilineal (adjective) (not comparable)
Concerning lineage or kinship through the male line: While being involved in the genealogy of her family, Alice was able to trace her patrilineal ancestry back to 1880.
rectilinear (adjective), more rectilinear, most rectilinear
1. Characterized by straight lines: Since Edward and his wife didn’t like flowery patterns for their wallpaper, they chose colorful one-dimensional, or rectilinear, patterns instead.
2. Etymology: "a straightforward line of descent", from Late Latin rectilineus which comes from the Latin words rectus, "straight" + linea, "line".

A lesser-known variant, "rectilineal", comes from the same Late Latin rectilineus and employs the -al suffix instead of -ar.

Rectilineal still shows up occasionally, but rectilinear is used much more.
