Milestones: Mar. 29, 1968

Married. Jonnie Miller, 23, adopted daughter of the swing era's top bandleader, the late Glenn Miller; and Frederick Swendson, 23, student at the University of Minnesota; in Pasadena, Calit.

Divorced. Gary Grant, 64, suave, handsome, debonair, altogether Hollywood's perfect gentleman; by Dyan Cannon, 30, sometime actress (Broadway's Ninety-Day Mistress); after 32 months of marriage, one child; in Los Angeles. Dyan and others testified that Gary had been "an apostle of LSD" for ten years; that he was subject to yelling and screaming fits," spanked her and hit her and promised to break her "like a pony," after which he would create "the wife I want" through the miracle of LSD. Grant denied all through his lawyers (he is in New York, recovering from auto-accident injuries), but Dyan got the nod from the judge, and $24,000 yearly in child support plus a $57,,000 settlement.

Died. Charles Chaplin Jr., 42, eldest son of the comedian; of a heart attack; in Hollywood. Bedeviled by his name ("Sometimes I wish I was called James"), Charles Jr, never rose above bit parts in such dreadfuls as High School Confidential and Teacher Was a Sex Pot. His one claim to recognition was a 1960 biography, My Father, Charlie Chaplin, a sometimes fatuous but often illuminating account of life with daddy.

Died Edwin O'Connor, 49, author of 1956's bestselling The Last Hurrah, a fictionalized account of the life of Boston's Mayor James Michael Curley; of a heart attack; in Boston. "A pale carbon copy," hooted Curley when the book came out. Carbon maybe, but pale never, as critics cheered ( nor's fascinating account of the last campaign of the boss of a big-city machine. The book sold over 125,000 copies the first year, went on to become a hit movie, and made O'Connor a fortune He wrote several other books (including Edge of Sadness, All in the Family) and a play (I Was Dancing) about the Irish in America, but none could match his first success.

Died Harry Kurnitz, 60, one of Hollywood's most durable and successful screen writers; of a heart attack; in Los Angeles. Bon vivant, ladies' man, globetrotter, Kurnitz was never one to bite the hand that paid him. "I write like Pavlov's dog," he said. "I just start typing automatically in the morning. And in 30 years, he cranked out more than 40 scripts, some bad but quite a few good, among them 1944's See Here, Private Hargrove, 1957's Witness for the Prosecution and 1966's How to Steal a Million. Broadway lured him, too and his Once More, with Feeling was a hit of the 1958-1959 season.

Died. Dr. Samuel Howard Miller, 68 Baptist minister and dean of Harvard Divinity School since 1959; of a heart attack; in Cambridge, Mass. Miller believed that "religion which is interested only in itself is worse than vanity; it is essentially incestuous, and throughout a distinguished career worked unceasingly to bring Christianity in tune with the secular realities of the times. A fervent ecumenicist, he called for an end to divisive tensions between Christians and Jews, between Roman Catholics and Protestants. Christianity, he argued, could only survive by bringing "new and deeper satisfaction to the human spirit."
