Robert (865-923) was of the Robertian line in France, which feeds into the Capetians.
Let’s begin with Genealogical tables, but please note: Sometimes the years are off by a year or so, compared with other sources I use.
This table is from the encyclopedia Medieval France.
Robert le Fort is Robert the Strong in English. Hugues le Grand is the same as Hugh the Great. Eudes is sometimes spelled Odo in English.
Here is Michael Idomir Allen’s Table 8, which he put together for his translation of Pierre Riché’s The Carolingians. This table offers an overview of the beginnings of the Robertians or Robertines:
The Robert who married Beatrix (Beatrice) is a proto-founder (of sorts) of the Capetians.
Here is Allen’s Table 4:
Rotbert is not a misspelling. Hugh the Great is the father of Hugh Capet, the namesake of the Capetians.

BASIC FACTS AND STORIES
Not as many scholars have done very much research on him (or I haven’t found one) as they have later royals. So here are the basics about him.
A Robertine or Robertian, he was born in about 865 and was the brother of King Eudes (Odo), whom he served. He turned against Carolingian Charles the Simple (the Straightforward, not simpleton) and defeated him in 920 and 922, but Charles remained powerful. Robert was elected king by a magnate Assembly on 29 June 922 and a day later was crowned at Reims, by Walter, Archbishop of Sens. Thus he was the second non-Carolingian ruler of West Francia (a much, much smaller version of a portion of the France we know today). But as noted, Charles was still alive and at liberty. He raised a force in Lotharingia and opposed Robert at Soissons in 923.
Robert died in the Battle of Soissons on 15 June 923, but Charles was defeated, for Robert’s son Hugh recovered the situation and Charles had to retreat.
Robert did not reign very long.
Herbert II tricked Charles into coming to a meeting and imprisoned him at St. Quentin, and so Charles was deposed again. Charles the Simple remained in prison at Péronne until his death in 929.
Unfortunately we don’t know much about Beatrix or Beatrice. One online source, citing the authoritative Europaeische Stammtafeln, says she was born c. 880.
Her name was fairly unusual in her own days (Bouchard, Those, p. 121). The Carolingian version of her name was Bertha. “A good proportion of the women named Beatrix in the eleventh and twelfth centuries can be demonstrated, on criteria other than simple name-similarities, to be her descendants” (Bouchard p. 121).
She died about 931.
Robert and Beatrix had three children:
1. Emma, who married Ralph of Burgundy;
2. Adela, who married Herbert of Vermandois;
3. Hugh, who became known as Hugh the Great.
