Maybe this will also help as another marriage is between Jacob Calvert Jr and Matilda Ann Daniel on February 19, 1835. Other Calvert marriages before 1850 are Ann, Cornella, Esther, Hannah, John (3 of them), Margaret, Marietta, Mary (2 of them), Nathan, Sarah (2 of them), and William. Any of these sound like you need them. The earlier ones are Hannah, 2 Johns (which might be the same person listed twice) and Nathan. The Shepard, Shephard, Shepheard, are Dorcas, Frederick, Hudson, Isaiah, Elizabeth, Rebecca and Phenis, but there are many many Shepherd and the Mary is not your Mary and Jacob. If you need any help let me know. Jerilyn
