HiI'm doing some research on Devenny families in the Raymoghy/Taughboyne area of County Donegal. I believe Isabella was baptised in Taughboyne in 1842 (https://www.ireland.anglican.org/cmsfiles/pdf/AboutUs/library/registers/Taughboyne/TaughboyneBaptisms.pdf) and married Robert in 1870 as I'm sure you know. I think I found a Flickr post where you note Isabella is Scottish.Her mother was Catherine Devenny according to the baptismal record - there are other Devenny families that emigrated to NZ so I am wondering if there is a connection?RegardsJason
