I have two Sarah Partridges in my tree.
Sarah #1 was baptised on 6 Feb 1785 in Letcombe Basset d/o James Partridge and Elizabeth nee Scribing / Scriving
I have the following siblings for Sarah #1
William 1781, Jane 1787, Elizabeth 1789, Elizabeth #2 1792, Ann 1793, Martha 1798
Sarah #2 was baptised on 17 Oct 1786 in West Ilsley d/o George Partridge and Elizabeth nee Poke. The family must have moved to Letcombe Basset when she was a child because her younger siblings were baptised there and her father died there in 1819.
I have the following siblings for Sarah #2
Martha 1777, Mary 1780, Elizabeth 1783, William 1789, James 1791, Richard 1799
There are two marriages in Letcombe Bassett for Sarah Partridges at the right sort of time.
One marries Charles Pembroke (of LB) on 17 Oct 1805, Lydia Pembroke, Elizabeth Partridge & Wm. Painter.
The other marries William Ackrill (of Uffington) on 19 April 1809, wits John Partridge & Wm Painter
I had the Charles Pembroke marriage down for Sarah #1 as they were first cousins, but he would be second cousin to Sarah #2, so still a possibility.
Witnesses to the two marriages don't really help. Both Sarah's had mothers and sisters called Elizabeth. Neither had a father or a brother called John.
Please can anyone help me to sort out which marriage is for which Sarah?
