Mariane was Grandpa's maternal grandmother. She was the mother of two boys and two girls, including Jensine Rasmussen, Grandpa's mother.
The Rosenholm archivist spells her name "Marianne", which is the more common spelling, but we use the spelling which is more common in the parish records.
Mariane died a day after her youngest child's 10th birthday, before Grandpa was born. She was 53 years of age.
