{ Short version: }
Ominis Gaunt and Liliah Robinson met in their 5th year at Hogwarts as they didn't get at first but eventually they did with or without their friend Sebastian Swallow getting in the way or not.
But by the time it was the year 1893 that's when Ominis got married to Liliah after Hogwarts graduation then together they ended the goblin vs wizard war in the year 1895 when they were both 20 but soon then Liliah found out she is pregnant and both Ominis and Liliah were happy.
In the year 1896 Alora Gaunt was born to Ominis and Liliah then in the Year 1898 Calistia and her twin sister Dracy was born but after their 3 daughters they decided to have more children in the year 1935 but into hiding before 1935 like the year 1930 is the year they went into hiding changing their last name to their family so Lord Voldemort wouldn't find them because Lord Voldemort was killing off their other family members of the Gaunt's /Riddles in his sight.
Ominis got his family out of there for the greater good then eventually settled down in Scotland.
Liliah hid their house with an ancient spell once they found their home in Scotland
It took time making their new home perfect.
Their home became perfect for them and soon they had 3 more kids so in total they had 8 kids together working and loving family but never discussed the past until their kids were ready to hear it
But until then the Gaunt's to the wizarding World remained dead until further notice.
But the 8 kids eventually learned the truth but once the 8 kids grew up and had kids of their own then just never went beyond their grandkids
So when the grandkids had kids the grandkids never passed down the message to their kids.
========================================
{Long Version:}
Ominis Gaunt and Liliah Robinson, initially clashing personalities in their fifth year at Hogwarts, found unexpected love amidst the hallowed halls. Their relationship blossomed, defying initial friction, even with the occasional interference of their friend, Sebastian Swallow. By 1893, Ominis and Liliah were married, their post-Hogwarts life quickly becoming extraordinary. In 1895, at the tender age of twenty, they masterfully resolved the escalating goblin-wizard conflict, a testament to their combined strength and ingenuity. The following years brought immense joy; Alora arrived in 1896, followed by Calistia and Dracy in 1898. Their family was growing, a beacon of hope against the darkening shadows of the approaching war.
The looming threat of Lord Voldemort, who was systematically eliminating their extended family, forced Ominis and Liliah into hiding in 1930. Abandoning their name, they sought refuge, eventually settling in the remote beauty of Scotland. Liliah concealed their home with an ancient, powerful spell, shielding their family from the looming darkness. Three more children joined their growing brood, bringing their total to eight. In their secluded Scottish haven, they built a life filled with love and hard work, carefully guarding their past until their children were deemed old enough to bear the weight of their legacy. The Gaunt name was effectively erased from the wizarding world's memory, a necessary sacrifice for their family's safety.
The truth about their family history was eventually revealed to their children, then grandchildren. Yet, the tale stopped there; it never reached the next generation. The Gaunt lineage, once a whisper of power and conflict, was quietly absorbed by the ordinary, the extraordinary sacrifices of Ominis and Liliah ultimately shaping a quiet, lasting legacy hidden within the rolling hills of Scotland, their family's past a closely held secret, a story known only to a few within their expanding family tree.
