The 1969 murders of actress Sharon Tate and six others by Manson's devotees were allegedly hatched at the Spahn Ranch.  Manson persuaded Spahn to permit "the Family" to live at his ranch.  Manson ordered the Family women to have sex with the then nearly blind 80-year-old.  The women also acted as seeing eye guides for Spahn.

Family member Charles Watson has written that his own nickname, "Tex", was given to him by Spahn, who recognized his Texas accent.

Baron Cromwell: Baron Cromwell is a title that has been created several times in the Peerage of England.  The first creation, which was by writ, was for John de Cromwell in 1308.  On his death, the barony became extinct.  The second creation came in 1375 when Ralph de Cromwell was summoned by writ to Parliament as Lord Cromwell.  His grandson, the third Baron, served as Lord High Treasurer to King Henry VI.  However, on his death in 1455 the barony fell into abeyance between his nieces Maude and Joan.  On Joan's death in 1490 the abeyance was terminated in favour of Maude, the fourth holder.  When she died childless in 1497 the peerage once again fell into abeyance, this time between the daughters of the first Baron.  The title remained in abeyance for over 400 years.  However, in 1922 the Committee for Privileges of the House of Lords reported in favour of the petition for the termination of the abeyancy of Selina Frances Bewicke-Copley, wife of Brigadier-General Sir Charles Watson Bewicke-Copley.

Selina died in 1923 and in July of the same year the abeyance was terminated in favour of her son Robert Godfrey Wolesley Bewicke-Copley, who became the fifth Baron.  He notably served as Lord Lieutenant of Leicestershire.  s of 2010 the ancient barony is held by his grandson, the seventh Baron, who succeeded his father in 1982.
