Anita - Brothers marrying sisters, etc. may not be so far fetched, after all. In the Pyeatt (Piatt) lineage we find, about 1700, the brothers, Jacob and Thomas Pyatt marrying the Hull sisters, Mary and Mercy, respectively. Then, in about 1790, the Pyeatt brothers (Maj.) Jacob and James married the Finley sisters, Margaret and Catherine, and emigrating as a group to (what is now) Arkansas in 1810. Then we find the son and daughter of (Maj.) Jacob and Margaret, John and Mary marrying Martha (Patsy) Carnahan and her brother, Samuel. The grandsons of (Maj.) Jacob and Margaret, John, Andrew (my ggf), and their nephew, Peter, marrying the daughters of Thos. H. Tennant, Margaret, Miranda (my ggm), and Nettie Tennant. These marriages span the family history from New England to North Carolina to Arkansas. On my mother's side, we have my gf, C.H.Roberts wed to Alice Hay, who bore him the first four of his eight children. She died in 1910, following the birth of my uncle, Chas. Roberts. C.H. Roberts then married Alice Hay's sister, Ninnie Lou Hay. I suppose that, should Ninnie Lou (Hay) Roberts have died, Clyde H. could have married the remaining Hay, Flora. I doubt seriously that these were all that isolated, as marriages went, and may still happen. There was strength in numbers in the past, and the group loyalty would be enhanced by sibling marriages. In fact, that is probably still the case. Don't discount it as a possibility, the evidence is right there, in the family history. Keep searching, and be prepared for pleasant and interesting surprises. Ed
