Claims that Engelram was the count of Flanders are clearly false (as is the assertion that he was the grandfather of Baldwin I).
Engelram was lay abbot of St. Peter's Abbey in Ghent, which could also have been the source of his title.
When Charles made a pact with his half-brother Louis the German in 864, he was named, along with Hincmar of Reims, as a guarantor on the behalf of the king.
In 868, he was sent with gifts to King Salomon of Brittany, and he acted as a guarantor again in 870, as reported in the capitulary of a meeting of Charles and Louis on 6 March 870.
