Words of Wisdom

If I had only 24 hours to live,
    Then the things that don't matter could wait.
I'd play with the children and hear all their stories;
    I'd tell you I love you before it's too late.

Bewahret einander vor Herzeleid,
    Kurz ist die Zeit, die ihr beisammen seid,
Denn ob auch viele Jahre euch vereinen,
    Einst werden wie Minuten sie euch scheinen.

Happy is the man who finds wisdom
    and the man who gets understanding,
for the gain from it is better than gain from silver
    and its profit is better than gold.

    Proverbs 3:13,14.

Intelligent people like to be near the ocean;
    kind people like to be near the mountains.

    -- Chinese proverb


My ancestors came to this country about fourteen generations ago. My great grandmother died young of tuberculosis and my great grandfather, who came from a good family, became a bootlegger. My grandfather was a farmer and my father an electrical engineer.

He joined the army around 1910 and was sent to the Philippines. He joined again around 1915 and served in New York. He worked at a number of jobs and finally was in the chicken business from 1929 to 1943. He told Richard that four Plaisted brothers came over to the US from England together. He also said that one of those known as Roger Plaisted was really named Edward.

Roger Plaisted II (1624-1675) Migrated to Boston, MA in 1650. Cause of his death was Killed by Indians in King Philip's War.

Lt. Roger Plaisted was killed by the Indians during the start of King Philips War, an attempt to kill all the white people in New England. King Philip's war is the bloodiest war in American history. There are two historical accounts of his battle with the Indians. He was greatly outnumbered. He fought bravely. Both he and one of his sons were killed. Samuel Plaisted, one of his grandsons, who graduated from Harvard in the class of 1715, was buried on the spot that Roger Plaisted was killed above Salmon Falls near Berwick, Maine. This gravestone is in magnificant condition even though it is more than 250 years old.

In 1675 the Indians made a determined and terrible assault on Berwick, and Lieut. Roger Plaisted, "like a man of public spirit, sent out seven men from the garrison to see what the matter was," and falling into an ambush, three of them were killed. The next day Plaisted went out at the head of a company of twenty, with a cart and yoke of cattle, to find the bodies; and, being surprised, most of the men ran for their lives; "while Lieut. Plaisted, out of the height of his courage, disdaining either to fly from or to yield himself (for 'tis said the Indians were loath to kill him, but desirous rather to take him prisoner) into the hands of such cursed caitiffs, did fight it out desperately, till he was slain upon the place. His eldest son and another man were slain in their too late retreat, and his other son was sorely wounded, so that he died within a few weeks after."

"Such," says Williamson in his "History of Maine," "was the fate of this Spartan family, whose intrepidity deserves a monument more durable than marble." The father had represented Kittery four years in the General Court, and was highly respected for his valor, worth and piety. He and his sons were buried on his own land, near the battle ground, full in view from the highway leading through Berwick, whose lettered tombstone tells succeeding ages: --

"Near this place lies buried the body of Roger Plaisted, who was killed by the Indians, Oct. 16, 1675, aged 48 years, also the body of his son, Roger Plaisted, who was killed at the same time."

Another Plaisted, Mehetable (b. April 30, 1670), a daughter of Roger, was captured by Indians at Berwick in 1690 and held captive by them in Canada till 1695. She married Thomas Goodwin after her return and had a son, Ichabod, in 1700.
