David a few details perhaps of interest---
In 1891 census when your grandfather was in
Strathallan Park orphanage they recorded his name
probably for first time -- Caren -- as you spell your family
name now. Also it looks as if he was allowed to
call himself his second Christian Louis as he preferred. Unusual in schools & institutions in past.
When he is with maternal Gran in 1901 the street is
only a few hundred yards from first home. A few houses
[not 3 ] still exist among banks /stores - 4 storey terraces with shops on ground floor. Hanover St. houses
were demolished long ago but the school red brick building is kept as Government Offices & Louis probably
attended when very young.
