A brother, Richard Fludd, settled in Ireland, where the surname is spelled Flood, while two of his sisters married Kent landowners.
The next year he was knighted and appointed a paymaster to the English forces fighting in France under Lord Willoughby, a post changed after much bureaucratic in-fighting to Treasurer at War in 1597.
Re-elected as Maidstone's MP in 1597, he was admitted to Gray's Inn in 1601 and was elected for the third and final time to the Commons in 1601, where he sat on a committee to consider the abolition of gavelkind.
In his will, proved on 11 June, he left small bequests to household servants, to the village church, to the poor in surrounding parishes and to the prisoners in Maidstone gaol.
In addition to his London house in Old Bailey, the landholdings mentioned in his will are predominantly in Kent but extend to Surrey, Sussex and his native Shropshire.
