Legal Definition
An immediate male descendant; the correlative of "father." Technically a word of purchase, unless explained. Its meaning may be extended by construction to include more remote descendants, such as a grandchild, and also to include an illegitimate male child, though the presumption is against this. See Flora v. Anderson (C. C.) 67 Fed. 185; Lind v. Burke, 56 Neb. 785, 77 N. W. 444; Yarnall's Appeal, 70 Pa. 341; Jamison v. Hay, 46 Mo. 548; Phipps v. Mulgrave, 5 Term, 323.
