Regarding the group photo:
Rootschatters helped with info about Arthur Kirk (one of the sons of the possible Kirk family in the photo) on this thread:
https://www.rootschat.com/forum/index.php?topic=832923.msg6975448#msg6975448He did join the army, the Northumberland Fusiliers, but was only in from 1911 until 1912, and emigrated to Canada in 1913. His short army career included detentions for striking a senior officer, being drunk in town, and urinating into a ration tin. When he was arrested and sentenced to 6 months in a civil jail for breaking a plate glass window, he was discharged.
Also on his recruitment papers, he gave his brother Samuel as next of kin. Previously he had been discharged from training ship Exmouth into the care of Samuel, in 1909. From this I'm assuming that the parents were dead by this date, although it was likely the parents were living apart (given the court case reported in 1901 about the father and cruelty to the children, and his comments about his wife in court). Samuel also stated at his wedding in 1911 that his father was deceased, but the children might have washed their hands of their father or not known if he was dead or alive. Possibly the mother was dead or in a workhouse by 1909?
Whatever did happen, it seems unlikely that this family would have posed for a photograph together!
Perhaps it is a photo of one of Samuel Kirk's sisters and her inlaws etc? Another lockdown project...
