The Northamptonshire Record Office holds considerable Bradgate information in its Holthouse Collection ...
My research within the Holthouse Collection at NRO was some 15 years ago, and primarily with regard to the Holthouse family and the German families into which they married.
I've just gone back to the collection to see what it holds for Bradgate researchers ...
The collection [HOLT] is numbered 1-691, of which 254-260, 414-438, 441-448 and 640-689 concern the Bradgate families. Some examples ...
254-260 Little Peatling, deeds/indentures 1596-1719.
434-435 Abstracts of wills 1603-1724.
437 Pedigree of Bradgates of Hellidon and extracts from wills and admons 1560-1937.
448 Pedigree of Bradgate family from Visitation 1683, York Herald, coloured.
640-664 Indentures/lease/chancery William, Edward Bradgate of Little Peatling 1610-1664.
666-681 Indentures/deed polls Edward, Thomas, Richard, William, Mary Bradgate of Hellidon 1669-1718.
... there is a summary of the collection, but the main catalogue of individual records is held in a card index.
Background to the Holthouse Collection ...
<i>"The collection was assembled by Edwin Hermus Holthouse (1856-1948), surgeon and eye specialist. He was the patron of the living of Hellidon, Northamptonshire (1881-1948)."</i>(NRO) Edwin was a great grandson of Carsten Holthouse, born Buchen, Germany, 1738, who came to London and began the family sugar refining business in the 1770s.
