Think it's time for me to walk away from this for a bit !!!!!
I had convinced myself that Isable Taggart appeared to be the daughter of Wm Harrison and Issable Harrison.
It's been a long weekend.!!!
Sorry for asking daft questions but I appreciate the response thanks.
Another daft comment ? I presume 'base' daughter means first child?
Thanks to you and Frances and Sue on this one !!
