My Mother has the unfortunate name of Elvire, named after her Grandmother, who was born in Belgium, the Daughter of a musician named Josephus Mans and Florence Nicholson, and as you know Elvire also had a brother called George.
The trail gets a little completed because somewhere between marrying Josephus and moving back to the north of england, she married a man from Malta called Girolamo Mamo, and had another two children, Gerald and William. When back in England they lived in South Shield and all Children took the surname Mamo.
I don't know much about Girolamo at all, but as the children he had with Florence had fairly short lives, and the fact that Florence married for a third time, I can only assume Girolamo died young.
Although I didn't keep up the study of my family tree please let me know if you find out anything.
By the way, the Mans family seemed to have originated from Holland.
