Looking for information on son of Pleasant Dunn, listed in the 1870 Tallahatchie County, MS Census as John S. age 10 born in MS. Never found again, he is thought to be John C. B. Dunn aka John Dunn aka Breckenbridge Dunn "Breck". Lived and died in TX, where other sons of Pleasant lived.
Pleasant's first wife Emiline died and he had remarried to Sarah Jones in next census, but no record of John. Pleasant had several sons that relocated to TX, and he planned to go there, but got hurt, and never joined them.
