  Frank D. Bumbaugh
  Frank D. Bumbaugh, the Capable and energetic vice-president and manager
  of the Monessen Foundry and machine Company, is a member of a family
  which has been most closely identified with the growth and development
  of the great steel industry, in that part of Pennsylvania. He is a son
  of James and Isabel (Peterson) Bumbaugh, both of whom are natives of old
  Virginia. Mr. Bumbaugh, Sr., was an expert financier, a pioneer in the
  iron and steel business in West Virginia, and operated one of the old
  charcoal furnaces of that time. He removed to McKeesport, Pennsylvania,
  in 1869, and was there identified with the steel and iron manufacturing
  business until his death in 1877. He was a descendant of a family which
  came originally from Saxony, Germany, the immigrant ancestor, Andrew
  Bumbaugh, having come to this country prior to the Revolution. The
  Bumbaugh family has been prominent for many years and furnished soldiers
  for the Patriot Army in America's war for independence. The original
  place of settlement was eastern Pennsylvania and from here the members
  of the family went to Virginia.

  In this same book it mentions William S. Bumbaugh b. in Morgantown, WV
  October 26, 1866 to James and Isabel. He was the youngest of 12
  children. His mother died when was 1 1/12 and he went to his sister's in
  McKeesport to live and at the age of eleven his sister died.
