Gilbert FitzRichard de Toneburge (Tonbridge) and Clare (b c1065, d 1114/7)
m. Adeliza de Clermont (dau of Hugh, Count of Clermont, by Marguerite)
1. Richard FitzGilbert de Clare, '1st' Earl of Hertford (b 1084-90, d 15.04.1136)
BE1883 reports that Richard "first bore the title of Earl of Hertford". However, TCP (Clare) notes that Richard "is often supposed to have been cr. Earl of Hertford by King Stephen, if not by Henry I. There appears, however, to be no ground for this belief." As so many sources follow the BE1883 numbering, we do so also but, in deference to TCP, show also the TCP numbering.

Presumably because she was several years older than her brother Richard, TCP suggests that Mabel may have been by an earlier marriage.

  (a) Thomas de Clare (dsp)
  BE1883 shows the following as daughters of Thomas, shown by BE1883 as 3rd son of Governor Thomas but named by TCP (Gloucester) as his heir, but TCP (Badlesmere and Clifford) identifies them as daughters rather than granddaughters of Governor Thomas.

b. Maud de Clare (b 1175/84, d 1213)
  m1. Roger de Lacy
  Various web sites show this as the Roger de Lacy who died in 1211 (## see here ##). Even if the marriages were the other way round, if the dates are to be believed, she could not have borne all his children. We hope to investigate this further in due course.

  A. Emma (d by 1168) shown by TCP (Wake) but not by BE1883 HJY
m. Hugh le Wake (d by 12.1176) HJY
  B. Margaret
  This Margaret is mentioned in TCP (vol X, appendix J) though the de Vere page suggests that this was wrong. BE1883 reports that a Margaret who was Baldwin's daughter married Montfichet but TCP (Pembroke) identifies that Margaret as sister of Gilbert, 1st Earl of Pembroke.

  Raymond is identified by BE1883 as son of William FitzGerald of Ireland. Basilia and Raymond are thought by some to be progenitors of the Grace family where reference is found suggesting that Raymond's father was named Walter.
  m2. Geoffrey FitzRobert
4. Alice/Adeliza de Clare (b c1080, d c1163) GHJSY
