I am at a brick wall as far as Alexander & Jemima, I cannot find birth or marriage information, and would appreciate any assistance. I am looking for family stories, pictures & genealogy of these families. If anyone has different information than mine it is welcome, as it is always best to know you are on the right twig of the family branch.

William (b. 1860, d. 1929) and Clara (b. 1867, d. 1924) are both believed to have been born in MA. The lived in CT for a number of years in Litchfield County and are buried in Winsted, CT.

Alexander (b. abt 1794, d. 1850) was born I believe in Southington, CT. Jemima (b. abt 1794, d. 1876) lived in the Norfolk-Canaan, Litchfield County, CT area for a number of years. Alexander is buried in Norfolk but Jemima's name is not on the headstone. Since she also lived in Sandisfield, MA for a time with her son, Andrew Parsons, (according to the 1860 census) she may have also been buried in that area.

Are they any Parsons cousins or researchers that can help? Thanks!
