Looks like you have identified Herbert! Crowhurst is interesting as I've found a lady there who

Really don't know.
The number
12 given in the newspaper for (Old) School Cottage may not be correct, but, anyway here is a
reminder of Harriett Savage and family in Denton in the free index to 1911

The other neighbours are John and Harriett Andrews.
Here's Harriett in the free index, age 50, a few years older than her husband. Harriett born London Cambdon Town

Though John Andrews (if it was the same chap) gave evidence for Mrs.Ainger.
Henry Ainger, husband, and John Andrews also gave evidence for the defendant.
1901, they may be in Crowhurst, Sussex, in Battle registration district.
Harriet Andrews, 40, born London Camden Town. Husband John is 35. They have a 13 year old adopted son with them.
