The Victorian lady who kept a Calling Book records a visit to York in 1883 and a visit to Sion Place, Sion Hill, Leeds circa 1888. It may be that the writing is 8 Sion Place.
It would have been nice to think that the Sion Hill that the lady visited was Sion Hill near Thirsk , which has had influential people living in it over the years.
I found the following entry in the Thirsk area:
Gentry & ClergyJoshua Crompton esq., M.P. Sion Hill
See Notes 1 and 2 below.
I found the following entry in Whites Directory of Leeds 1872:
List of West Riding MagistratesHon George Edwin Lascelles
Sion Hill, Thirsk
See Note 3 below.
I was hoping that Constance Lascelles of Queens House, Lyndhurst might have been the Lady! But a visit to the Christopher Tower Referenece Libray in Lyndhurst disproved this:
Visit to Christopher Tower Reference Library
Notes:
1. Also under Gentry & Clergy in Thirsk was a Thomas Buckle of Sowerby; the Victorian lady met the Misses Buckle in York.
2. Also under Leeds in Pigot's Directory were clergy names Fawcett; a well-known name in the Lymington area.
3. The 1881 Census shows that the Lascelles had a substantial household at Sion Hill.
