I have ordered this book from the higgins publishing co... it is available... but also out of print therefore to order the book be prepared to spend nearly 100.00 also... there was a previous post to a website that has up to 10 generations of ikenberry's (spelled numerous ways) i have to say there is a ton of inbreeding between floras, ikenberrys, bowmans, and barnharts. hahah but i guess in that day they didnt have much choice... this website stops with my great great grandmother catherine hirt/henry ikenberry... but its a great help if u can understand the numbering system... took me a few mins to get it down... but the website it...
