I've just found I have an Ibbotson link in my family history. One of my g.g.g.grandparents was Hannah Ibbotson, b.1817 in Kirby Wiske, North Yorkshire. Siblings that I know of are: Margaret b. 1806, John b.1808, Francis b.1810, Lavinia b.1801, Mary b.1803, Thomas b.1813 and Mark b.1815. Their farther was Francis Ibbotson and mother Sarah Finckle (possibly Finkle). Hannah married Francis Hawksby (could be Hawsby) in 1883, again in Kirby Wiske. (If you can't find KW on a map its between Thirsk and Northallerton, north east of Leeds).
Anyone think they might have a connection - let me know!
