Ida "secunda" de Longespee?

It seems that William de Longespee William Longespée, 3rd Earl of Salisbury and Ela of Salisbury Ela, 3rd Countess of Salisbury suo jure may have had a second daughter Ida, who married Walter FitzRobert of Woodham (lots of these Fitz guys running around!)

Medlands reconstructs the situation thusly:

9. IDA Longespee (-after 10 Apr 1262). The Book of Lacock names “Isabellam de Vescy…Elam…Idam de Camyle” as the daughters of “Guillelmus Longespe ex…Ela”, adding that Ida married “Walterus filius Roberti” by whom she had “Catarinam et Loricam…velatæ…apud Lacock, Elam, quam duxit primo Guillelmus de Dodingseles, de qua genuit ---, Robertum, qui Dernogoill ---“[1806]. This second daughter called Ida must have been a different person from his older sister also named Ida, as the latter received dower from her second husband William de Beauchamp after his death in 1260, so clearly could not have married Walter FitzRobert before 1247. m (before 1247) WALTER FitzRobert of Woodham Walter, Essex, son of ROBERT FitzWalter of Woodham & his second wife Rohese --- (-shortly before 10 Apr 1258).

WALTER FitzRobert of Woodham Walter, Essex, [only] son of ROBERT FitzWalter & his second wife Rohese --- (-shortly before 10 Apr 1258). Bracton records an inquiry, dated 1234/35, whether "Cristiana de Mandevilla soror Walteri filii Roberti" was seised of part of land "in Dersingham", which descended to her "ex parte Gunnore matris sue" and was inherited by "Henricus de Bailloil et Lora uxor eius" because "idem Walterus non fuit frater predicte Cristiane nisi ex parte patris"[921].

m (before 1247) IDA de Longespee, daughter of WILLIAM Longespee Earl of Salisbury & his wife Ela Ctss of Salisbury (-after 10 Apr 1262). The Book of Lacock names “Isabellam de Vescy…Elam…Idam de Camyle” as the daughters of “Guillelmus Longespe ex…Ela”, adding that Ida married “Walterus filius Roberti” by whom she had “Catarinam et Loricam…velatæ…apud Lacock, Elam, quam duxit primo Guillelmus de Dodingseles, de qua genuit ---, Robertum, qui Dernogoill ---“[922].

Walter & his wife had four children:

1. ROBERT FitzWalter (Henham 1247-18 Jan 1326).

2. CATHERINE, nun at Lacock.

3. LORICA, another nun at Lacock.

4. ELA . The Book of Lacock names “Isabellam de Vescy…Elam…Idam de Camyle” as the daughters of “Guillelmus Longespe ex…Ela”, adding that Ida married “Walterus filius Roberti” by whom she had “Catarinam et Loricam…velatæ…apud Lacock, Elam, quam duxit primo Guillelmus de Dodingseles, de qua genuit ---, Robertum, qui Dernogoill ---“[927]. m firstly WILLIAM de Dodingsells, son of ---. m secondly ---.

Walter's father, Robert FitzWalter of Woodham, was the son of Walter FitzRobert of Dunmow and the grandson of Robert FitzRichard de Clare. Details here: http://fmg.ac/Projects/MedLands/ENGLISHNOBILITYMEDIEVAL3D-K.htm#Wal...

A different reconstruction makes this Ida the daughter of Sir William Longespee Sir William Longespée and Idoine de Camville Idoine de Camville, Countess of Salisbury, which also works if you get the dates lined up right. (Idoine was at most a "courtesy" Countess, as her husband predeceased his mother and never actually held the title Earl of Salisbury.)

This would appear to be the couple in question:

Walter Walter FitzRobert, Lord of Little Dunmow
