Alexander Mervell was born on June 27, 1829, as the slightly elder of twin brothers to Hubertus Mervell and Marie Mervell-Hoff. His twin brother's name is August Mervell. Alexander was born on the Mervell estate in the city of Lutheria.

Alexander grew up in high society, mainly with nannies, as his parents were often abroad for business or (inter)national affairs. At the age of ten, Alexander and his brother August were sent to boarding school, where they were expected to study economics and law. Life at the boarding school was difficult right from the start, but Alexander proved to be an excellent student. He excelled in his exact courses and had a natural charm that allowed him to quickly form close relationships with the people he met. Alexander quickly became popular among both his classmates and teachers.

Alexander, with his love for numbers, started his career as a banker in the cities of Lutheria and Alden. He acquired several funds to revive the city of Lutheria, which had fallen into disrepair. He restored many monumental buildings, funded local schools and religious institutions, and put Lutheria back on the map as a center for religion and trade.

While on a local masquerade Alexander was introduced by his father to Mary Argos, which he found a suitable partner for his son. Mary was of nobility, her parents being successful traders and Mary destined to take a prominent part in her parents business. After the dance, the couple decides to get to know each other better and a fondness between the two started to grow.

Alexander Mervell and Mary Argos got married on February 2, 1855, after a year of courtship. The wedding was celebrated in the town of Lutheria, and it was a grand event with the main streets decorated like a royal wedding. Despite their quick marriage, the couple proved to be a great match, both romantically and intellectually.

Paulus Mervell was born on June 17, 1858 at the Mervell estate in the city of Lutheria.

Felix Mervell was born on October 28, 1862, at the Mervell estate in Lutheria.

After having two children, Alexander made the decision to prioritize spending time with his family. His career as a banker demanded much of his time, forcing him to be away from his family frequently. In an effort to avoid a similar upbringing for his children, where they were primarily cared for by nannies and tutors, Alexander chose to become a long-term investor and spend all his spare time with his family.
