I've posted this in the past and hope there might be some new Robinson list members.  I have a huge brick wall which I can't break down. My 4th gr-granfather, William Robinson, born 1805 in Delaware; died 1865 Marion Co, IN.  Married to Catherine May (1812-1863).  They had at least four children as per the 1850 Fountain Co., IN census (could have had more per 1840).  son David H. - my 3d great-grandfather son John W. (I have his entire line info) dau Margaret M. - born abt 1835 in IN dau Francis A. - born abt 1842 in IN My brick wall is the two daughters, Margaret and Francis.  I cannot find then in 1860 even as Robinsons.  The only information I have, which may not even be them, is that in Webster Co., Iowa there is a Margaret Robinson md. to a Thomas Walton in 1888 per marriage index; and in same Webster Co. there is a Francis A. Robinson md. to a Harry Cragg in 1866.  I have not been able to find either of these two couples in any census at all or even in any death index, etc.  So, the names I have been trying to find together are Robinson & Walton and Robinson & Cragg or even the two sisters as Robinsons, thinking they never married.  I realize too that it is possible that both died before 1860 census.
