Cherese, refer to my previous post. I just wanted to add another piece of useless information. Jan Albertus (1850) was a good 18 years younger than his sister Johanna Sophia Schoombee. This sister was the first wife of the Frederik Jacobus Schoombee mentioned in your post. In other words Frederik married his cousin. This explains how the Jan Albertus name was carried into Frederik's branch of the family and it also explains the slightly later date of birth (1861).
