Your articles are located in the Livingston Parish History Book "the big Book" as we call it. When I saw the reference on the Pendarvis info, I went and opened up mine and found both articles. If you do not have this book and do a lot of research in Livingston Parish, you need a copy. It has the history of hundreds of families in this area.

, and I will tell you how to get a copy. If you are in this area, the library has them for sale or I can tell you how to find the address for ordering.
The history book was published in 1986, so there was probably no Register that year. I thought I had most of them and was surprised I did not have it when I looked so that may explain.
The dues for ELHA are $10.00 a year and with that you get four ELHAgrams published during the year. Let me know if you are interested in this also.
