I have a bio on a Am Withrow who was married to a Mrs. Margaret Hunter a widow of Daniel Hunter. Margaret was the daughter of Leander and Rebecca [Kinney] Pickard both natives of New York who had came here to Illinois in 1854 settling in Bureau county, and later to Henry county in about 1869. Margaret and Am Withrow apparently were childless but the bio states that she was the mother of six by her marriage to Daniel Hunter. The material contains a brief amount of information on those children, and also it includes the same on the surviving five children of Leander and Rebecca at the time the bio source volume was published in 1910. If you feel this material might hold anything of interest for you I would be happy to forward it.
