In that year the converts petitioned the King for a Keeper who would look after their interests. It is noted that during the next hundred years many of the Keepers of the Domus Conversorum were also Keepers of the Rolls.
However, the King answered the petition by fixing the allowance for the House at £202: 0: 4, out of which the Fabric was to be kept up, the Master, Chaplains, and Clerk were to be paid, and the converts were to receive weekly allowances. On the death of a convert the amount of the grant was to be decreased. It was evidently supposed that the converts would die off. This, however, did not take place. On the other hand, though the numbers rapidly decreased, the House was never without new converts. Mr. Phillimore does not say where these converts came from: if there were no Jews left in England there could be no converts made in this country.
In 1308 the converts complained that their allowances were not paid. The King ordered an inquiry. It was found that out of all the inmates in 1290, 34 were dead, twelve had left the House, and 56 were still living there. The King thereupon granted a reduced payment of £123: 10: 6.
In 1330-1 there were 8 men and 13 women converts.
In 1334 there were 7 men and 13 women.
In 1337-8 there were 13 men and as many women.
In 1350 there were 2 men and 2 women.
In 1351 Henry de Ingleby had only 1 convert under his care.
In 1371 William de Burstall, who was Keeper of the Rolls, was made Keeper of the Domus Conversorum: there were then two converts. In 1377, on learning that William de Burstall had repaired the dilapidated buildings, Edward the Third provided that the two offices should be held together.
In 1386 payments were asked for the Keeper, one chaplain, one clerk, and three converts.
