      Dear Rod, 
      I am searching for information on William Bigelow who married Mary
      Murphy. They are my gggrandparents. I believe that William is the
      son of Loring Bigelow 
      and Prudence Penniman. Loring married first Anna Maria Mooreman,
      and then Priscilla. William's daughter, Sarah, was my great
      grandmother, born Aug 27, 
      1871, Detroit, Wayne Co, Mich. She married Frank Herman Merritt,
      and then after his death she married a man named Bowhall. She
      lived in Davison with Frank 
      later in life, before his death, and in Owosso with Mr. Bowhall.
      Sarah and Frank lived all over Mich, and in Minn for a time--their
      children were all born in different 
      cities--no 2 in the same one. Sarah died in Owosso, Mich in 1937,
      and is buried beside her first husband Frank, in the Davison
      Cemetery, Davison, Mich. Is 
      there anyone who might have information on Loring Bigelow? Loring
      would have been William's father, and he did purchase land in
      1835, in Wayne Co, Mich, 
      near Romulus. He is thought to have had a son named William by his
      second wife, and there is a William living in the same household
      in the 1850 Wayne Co, Mich, Census, who was born about 1829, and
      would have been 21 years of age--about the right age to be Sarah's
      father. I do know that Loring is buried in Romulus, Mich, near
      where his farm was. If anyone knows anything about Loring Bigelow,
      born in Sullivan co, N.H., 1806, son of Ezekiel Bigelow, and
      descended from the first John Biglo mentioned on the Bigelow
      Society page, 
      PLEASE contact me. I am unable to varify this without help. 
  It has been some time since I last wrote to you.  You
      may not recall it--it was some time ago.  I have been digging
      and digging trying to locate my William Bigelow, who married Mary
      Murphy.  They are the parents of my ggrandmother, Sarah
      Bigelow, born Aug 27, 1861, Detroit, Wayne Co, Mich, and died 1937
      in Owosso, Mich.  Sarah was married twice.  First to my
      great grandfather, Frank Herman Merritt, with whom she traveled
      and moved a great deal--so much so that each of their children
      were born in a different city, either in Mich, or Minn.  She
      later married a man named Bowhall, and lived with him in Owosso,
      until her death.  She is buried in the Davison, Mich
      cemetery, next to Frank. 
         I know that Loring Bigelow had a young man named
      William living with him in the 1850, Wayne Co, Mich census. 
      Going by the dates, it appears 
      he was born about l829, and would be just about the right age to
      be Sarah's father.  Loring's farm was located in Romulus,
      Wayne Co, Mich, and he is buried there.  I know that he is a
      son of Ezekiel, and descended from the first John Biglo mentioned
      on the Bigelow Society 
      webpage. 
          This is the only clue I have been able to find
      that might lead me to the generations previous to Sarah and her
      father William.
