If anyone has any Ray ancestors from Central Kentucky, who migrated there from Maryland, I encourage you to locate and review this fabulous book.
The Ray Book: A Family of Central Kentucky, 1705-1993
by Ann Tyson Sipes, Louisville, Kentucky: Historical Research Publishers, 1993.
It is a lengthy book, about 1,200 pages with an index. It is well researched, with sources. Some of the information will be quite unique, as the author received letters, family trees, and copies of obituaries from members and descendants of the Ray Family that may be difficult, if not impossible, to locate elsewhere.
I have Ray ancestors and found this book invaluable. My great grandmother was Sarah Catherine Ray, born in Hardin County, Kentucky.
Many of the Catholic families that originated in Maryland in Colonial America days, later migrated together to Central Kentucky. The Ray Family is one of those families. This book is a wealth of information. A researcher can use it as a source and as a finding aid to locate sources she herself used in writing the book.
I highly recommend this book.
