Like most families, the Longpré family has issues in tracing ancestors. For the longest time we wondered if we are even part of the Longpré clan as my great-grandfather carried the name Lampron which was passed on to my grandfather. However the family name was changed to Longpré. So which family do we actually belong to?
Well, to be honest, there is a marriage certificate between a Joseph Lampron and a Louise Lord in 1866. Louise was my great-grandfather’s mother. It seemed “game over” for the debate. Accept, there was this issue of DNA relations that are all from the extended Longpré family going back to a marriage between Guillaume Longpré and Catherine Bleau. Every branch of the family from that couple has provided a large group of DNA relations. The waters became muddy all over again. Now to be fair, I have more than 37,000 Ancestry DNA tested individuals from my father’s line.
That’s a lot of contacts, too many for me to deal with, so I got AI involved. Long story short, there are no DNA matches found in the Lampron clan. None! There is a story that Joseph Lampron married a pregnant Louise Lord, yes, stuff happened even back in the past. Now, just to figure out who impregnated the young woman, DNA was cited that it had to be a Longpré or else the huge number of Longpré clan couldn’t exist. If it was neither a Longpré or a Lampron, then neither clan would be our family.
Given the overwhelming DNA evidence, a reluctant AI was forced to admit that there was no probability of Joseph Lampron being a biological father to Raphael Lampron/Longpré. More than that, the probability of it being a male Longpré as the father was near unanimous. Yet, AI was reluctant to let go of Joseph Lampron because of the marriage certificate. AI wants everything cleanly documented and searched for days for a document which would have a different Joseph [Joseph Allard dit Longpré], son of Jérôme Allard dit Longpré, admitting in writing that he impregnated Louise which then led to her parents marrying her off to a younger man, Joseph Lampron. Good luck ever finding such a document.
So, the task became clear. What does the DNA trail story tell for all the descendants of Jérôme? Strangely, a host of DNA relationships. Case closed. We are indeed Longpré. I already had some proof of this before I began as my friend Yann Longpré published a two-volume book filled with as close to all the names of the Longpré clan as could be found. And yes, he arrived at the same conclusion, years before AI had done the same for me.
