I need help!!! According to the 1850 Loudoun Co census there are 3 Peter Compher's listed:

Peter Camphor age 74
Catherine Camphor afe 65
Jno Camphor age 30
Sarah Hamilton age 45

Peter Compher age 58
Martha Compher age 62
Wm Compher age 27
Betsey Compher age 32
Margaret Compher age 25

Peter Comphir age 37
Mary Comphir age 34
Victoria Comphir age 9
Sarah Comphir age 7
Wm Buffeton age 58
Darcus Jackson age 65

How are these 3 Peter's related? I'm assuming the first Peter born abt 1776 is the son of John & Maria Cathren Cpmpher. I know this Peter is buried in New Jerusalem Lutheran Church Cemetery. Who were the wifes of this Peter?

The 2nd Peter was born abt 1792 and I'm assuming he is the son of the Peter born abt 1776. Who was his mother? I'm also assuming the Martha on the census is his wife? Did he have other wife's? This Peter is buried in New Jerusalem Lutheran Church Cemetery.

The last Peter was born abt 1813 and I'm assuming he is the sson of the Peter born abt 1792. Who was his mother? I'm also assuming the Mary on the census is his wife? Did he have other wife's? Where is this Peter buried?

There is a Peter Compher born 3/27/1812 died 3/18/1885 buried in Arnold Grove Mthodist Episcopal Church Cemetery, is this the Peter born abt 1813?

Any help will be appreciated.
