Check out the 1820 census for this Clow family - I have a listing of their children's birth dates, marriage dates, etc., and have charted them as to M/F and age groups as per the 1820 census classifications.
It is fascinating to note that the breakdown for males in this family COINCIDE exactly with those shown on the 1820 census - INCLUDING the first John Clow!
5 males under 10(Stephen, Andrew, Philip,Calvin, Elias) 1 male 10 - 16(John William, age 15) 1 male 16 to 26(John, age 16!!) 2 males over 45(Andreis, and his father John)
The females also match exactly except there is one extra female, over the age of 45.Was Bata Clow possibly still alive at this juncture?Or possibly Catherine's mother?)
I certainly think that there is something in this line of thought, and it is worth pursuing further.
Also, you mention that the name LEE appears as a middle name in this family and wonder where it came from. One thing I have noticed in going over records in this time frame is the proclivity to give sons' middle names of current well-known political figures.
I have several 'Nelson' and "Horatio Nelson' middle names in my family in the early 1820's, after the heroic Lord Nelson of British Naval fame.It really threw me at first as I followed down every family tree looking for a 'Nelson' link, only to finally realize that one out of every 20 males in the neighbourhood had the same middle name!
I also have quite a few "George Washington"s, and even a few "Bonaparte"s in my family tree.Was Byron Lee Clow, by chance born during or shortly after the Civil War (1860's?)General Robert E. Lee was a much admired man by both Union and Confederate sides.He spawned a liberal dose of 'middle name' entries for posterity.Just a thought.
