I have highlighted areas I need to look up or that sound like they might fit together....

P. M. WALLOVER, an extensive oil producer and refiner of Smith's Ferry,
  Beaver county, Pa., whose portrait appears on the opposite page, was born
  near Philadelphia, Pa., in 1824. Several generations of the Wallover family
  were born in that vicinity. The birth of his father, William H., and of his
  grandfather, after whom he was named, also occurred in that part of the
  state. His grandfather, M. P. Wallover, was the son of a well-known sea
  captain. He was reared and educated in the city of Philadelphia, and at an
  early age became interested in the manufacture of paper. (?) Why would he come aboard ship?  Same person, then? In those pioneer

days all the work was done by hand, and to do an ex-

  tensive business required considerable capital. He was successful in his
  operations and established two mills, one on Mill Creek, the other on
  Wissahickon Creek. He became very wealthy. At that early day, only wealthy
  people could afford to buy a piano, and he bought one of the finest
  instruments shipped to this country. The whole family became expert players
  on this instrument.
  
  He reared a family of six children, namely: Peter; William H.; Harry, who
  went to Mexico, and there formed a partnership with a Mr. Bellfield (both of
  whom showed their patriotism by offering their place to the government for a
  garrison); Harriet, who became the wife of a Mr. Duckett, a wealthy paper
  manufacturer; Margaret (Shee); and Mary Ann.
  
  William H. Wallover, father of the subject of this sketch, obtained his
  intellectual training in Philadelphia, and, although the ad-vantages were
  meagre, he received a fair education. His first business relations were those
  with his father, whom he assisted in the paper mills. He was interested in
  that business during all of his active career. He married Harriet Mervine,
  and they reared three children: P. M., the subject of this sketch; Anna, the
  wife of General Daniel Dare; and Henry, who died at the age of six years.
  
  William H. Wallover died in 1829, and his widow married a Mr. Stott, a
  mechanic of no mean ability. He it was who put the machinery in the United
  States steamship Prince-ton. He was superintendent of the Phoenixville Iron
  Works for many years, and retained this position up to the time of his death,
  which occurred very suddenly.
  
  P. M. Wallover received his education under private tutorship. He learned the
  trade of a machinist, but, although he never followed it, he has found his
  knowledge of mechanics very useful during his business life. His first work
  was in a paper mill of his uncle, near Philadelphia, where he labored for
  eight months; he was then given the management of the establishment.
  Afterwards he became interested in two mills, working them on shares, - and
  continued thus until 1854, when he came to Beaver county to manage a mill
  opened by a relative on Little Beaver Creek. This mill was operated for three
  years. Mr. Wallover purchased property near Smith's Ferry, and on February 9,
  1860, he began to drill for oil. March 1, of that year, he struck a
  five-barrel well. This gave him encouragement, and he leased more property
  and struck a well which produced $60,000 worth of oil. He has drilled and
  operated twenty-eight wells, and all of them were good producers.
  
  In 1863, he started an oil refinery, - it being the first one in this
  district. He at once began to experiment in the oils, and his efforts were
  crowned with success. He made the first signal oil used on the Ohio River; he
  also made the first brand of wool oil used in the woolen mills, and got
  several brands of fine machinery oil. In those days the war tax was twelve
  cents per gallon, and one dollar per barrel. The firm name of the refinery
  was the Wallover Oil Co., but there were three

  parties interested in it. Two of them were railroad men, and when the
  railroad was put through that section, the railroad partners had to withdraw
  from the Wallover Oil Co., as it was against the rules of the railroad
  company for any of its stockholders to hold outside interests. Consequently
  Mr. Wallover purchased their shares and continued the business alone.
  
  Our subject was joined in the bonds of wedlock with Margaret Arthur. She was
  also born in Philadelphia. They have a family of eight children: Charles A.,
  now engaged in paper manufacturing; William H., who is in the oil business,
  in Indiana; Robert A., who is with his father; Joseph D., a contractor for
  drilling oil wells; Bert S., deceased; Edwin S., a salesman and teacher of
  music; Katie, deceased; and Laura (Boyd). Mr. Wallover is a Republican, and
  has served in minor offices of his town. The family is in accord with the M.
  E. church, of which he is a liberal supporter.
