Lady Charlotte Lee had well-known children by her first husband, Lord Baltimore.
Her monument, at Woodford, Essex, indicates a daughter by Christopher Crowe:
MORTALITATIS HIC SUE EXUVIAS / DEPONERI VOLUIT / NOBILISSIMA DOMINA CHARLOTTE LEE / EDWARDI HENRICI COMITIS LITCHFIELDIAE / FILIA NATU MAXIMA / BENEDICTI LEONARDI BARONIS DE BALTIMORE / DEINDE / CHRISTOPHORE CROWE ARMIGERI / CONJUX / OBIIT XXII JAN.

"Filia Natu Minima" implies other daughters, and the commentary mentions a daughter Catherine, wife of Roger Henry Gale of Scruton, as well as two sons, Christopher and George Crowe, which George had a daughter Barbara Crowe (named after Charlotte Lee's grandmother, Barbara Villiers ?).
The HOP sketch of Lord Baltimore indicates he separated from Lady Charlotte Lee in the year 1705:
The sketch says more about the rocky course of their marriage: "The following year he married a daughter of Lord Lichfield, on which occasion his father settled £1,000 a year on him, and Lord Lichfield gave him the rangership of his own park at Woodstock. Lichfield was displeased, however, when Lady Charlotte turned ‘papist’ in October 1699 after the birth of her first son, despite his ‘utmost care to have her well grounded in the Protestant religion’. The couple separated in 1705, in which year Calvert received an unexpected windfall when the Duke of Marlborough (John Churchill), who had been granted Woodstock by Queen Anne, had the rangership purchased for him for £6,450 by the Treasury. Calvert’s father, who still received rents from the planters in Maryland, though with a diminished income as his house there had been plundered and his accounts and papers destroyed, was still allowing him £600 a year and paying for the education of his six children in Catholic schools abroad. In February 1711 Calvert sought a divorce from his wife in the Lords on the grounds of her ‘open adultery’, having obtained ‘a sentence of divorce in the Arches Court of Canterbury without any proof of recrimination’. However, the bill did not succeed."
The first husband died in August 1715, which leaves plenty of time for her ca. four children by Christopher Crowe of Kiplin, Yorkshire, and Woodford, Essex.
Here is her marriage settlement with her first husband Benedict Leonard Calvert (late Dec. 1698) ...
