Looking for Descendants of Aubrey Family from Herefordshire

I have been tracing and writing up the story of Morgan Aubrey, (1527-1608) of Clehonger in Herefordshire and his descendants.

I am now searching for information concerning those who moved to the U.S. and N.Z in the 19th century.

What I have found so far can be read in 'Salt & Silk - chronicles of the Aubreys of Clehonger', and 'Silk and Sons - how an Aubrey married the Lord Chancellor's daughter'.
