Can anyone help me with family history/tree information about descendants or ascendants of the following?

Hannah Gatch, born 19 December, 1807 in Clermont Countyr, Ohio, USA, died 14 December 1844 at Piqua, Ohio, USA & Jacob Gest Dimmitt, born 1 March 1806, died 20 November, 1872 at Des Moines, Polk County, Iowa, USA.. Jacob & Hannah married in 1852 in Clermont County, Ohio, USA & had 6 children: Lydia Ann, John S. 1826-1860, Margaret Gatch 1826-1869, Milton Maley 1838-1861, Wilbur Christie 1841-1864 & Sarah Melvina 1843-1843.

As I research my families widely, both for my own family tree purposes and as a gift to friends and their families, I would really appreciate any family tree and relevant research copies from anyone in any country who is researching the name, or perhaps some leads to already existing websites where this type of information can be found.

If anyone wishes to send me information, either a Gedcom or a file attached to an email would be very welcome. I would be quite happy to send anyone who requests it all the information I have in return. I run Legacy 6 as a genealogy programme on my computer
.

Thanks for your assistance, everyone.
