I am posting this information as a courtesy - I am not a Bright desc. and have no other data.
A book titled 'Index to Pennsylvania's Colonial Record Series', compiled by Dr. Mary Dunn, provides data listed below for various persons named Bright. I have a copy of the 3rd edition which was published 1996 by Genealogical Publishing Company, Inc. of Baltimore, Maryland. This book provides index data only; that index data must be used with the actual volumes of the Colonial Record Series, which are not available to me.
Jacob - 11:56 & 536, 13:102 & 183, 16:451 Joseph - 15:155 Michael - 10:430, 491 & 652, 14:480, 15:34,84 & 386.
Bright & Salter - 15:34
I hope that this posting is helpful to a serious Bright family genealogist or historian.
